Simple free energy. ... or is it? This one has come back up for review (July 15, 2018)
This is not my video actually... and I had a stupid spell on this one and forgot to make a note of where I GOT it ....
This video is misleading and does not demonstrate free energy, unless the coils hold electrets instead of batteries, and I'll explain why, below.
Corrections and remarks are in red color.
It is known that when a magnet spins over a coil, there is resistance. Why is there resistance? Because the spinning magnet induces a magnetic field into the coil that opposes the magnet's movement -- it induces the same magnetic pole into the coil, slowing down the magnet when it enters near the coil, due to inducing a repulsive field, and then attracting the magnet as it moves past. But ...
Resistance is the magnetic effect of inducing a like-to-like magnetic field in a coil that repels the magnet when it approaches, and attracts the magnet when it leaves. This is why there is magnetic braking effect in any kind of electromagnetic generator setup.
Say the magnets are south pole facing down. When the south pole starts to move and cut across the coil, it induces a magnetic field that opposes its movement. When it passes the the midpoint and moves across the other side, it induces the opposite flow of electromagnetism, which reverses the pole of the electromagnet in the coil.
This one had truly caught me off guard because I wanted it to work. There is a magnetic reed switch involved in the system.
I have to say now that this system will work if the coils contain electrets inside it (batteries that never die). It can work if batteries are inside it too, whereas the bolts were cut and re-glued to make it look like the bolt goes all the way through. Then as the magnets close the circuit on the magnetic reed switch, the batteries inside the coils induce a magnetic field which repels the magnets away and speeds it up.
I truly failed my discernment test on this.
The coils connect to the LEDs. The coils are oriented in the same direction. The magnets are oriented in the same directions (for example north pointing up). The coils are connected in parallel. It looks like a magnetic reed switch of sorts as an on/off switch, or otherwise a solid state magnetic sensor which completes the circuit when not in the vicinity of a magnetic field. The coils are wound around cylinders bolted down to the clear plastic plate.
Note that the overhead magnets pass in a circular arc over 1/2 of the top portion of the magnet, so to maintain the same polarity as it passes over the magnet. Also note, a magnetic reed switch can be used to complete the circuit when the magnetic field causes the reed switch to close (little metal plates that when magnetized in the presence of a magnetic field close together, closing the circuit). But what is used in the video looks like a solid state component.

Actually, if I'm not mistaken, the LED is a diode that makes the electromagnetic current go in one way only. If coils were straight-connected to each other, then as the magnet passes by, it will encounter resistance from inducing the same pole into the electromagnet coils as the pole passing by (or over, in this case), from the magnet. That's what the little reed switch thing is for, is that it leaves the circuit open until the magnet is overhead and then closes the circuit, connecting the coils to each other. The magnets are already in motion at that point, the coils are induced and the little LED PREVENTS the magnetic field from collapsing, so the coils stay charged with an electromagnetic field which gives the magnets a push. The circuit then opens back up when the magnets are away at a sufficient distance, so the magnets don't encounter resistance that slows them down when they approach the coils again.
This is wrong. An LED does not prevent the magnetic field from collapsing, which does so in the opposite polarity of the electromagnetic field that had built up. A Diode prevents electric current from flowing in the opposite direction but does NOT prevent the magnetic field from collapsing.
The coils will resonate with each other, and slowly deplete their energy (their magnet), until the circuit is open and the resonance stops. If the coils were strong enough, when the circuit opens up, a little spark may jump across the gap in the open circuit as the coil fields rapidly collapse.
When an electromagnetic field collapse occurs, without a diode, then the collapsing field actually reverses direction and thus reverses polarity. Without the diode, the reversed electromagnetic field would pull the magnet back, and the whole system would begin oscillation (back and forth) instead of rotation.
This is wrong, too. Even with a diode, an electromagnetic field will collapse. The diode just blocks the current at that point from flowing through the wires, however the field will collapse where it's at, in the way electromagnetic fields do, regardless. The diode prevents it from back-feeding through the system, and the components start to get hot.

Here below are simple dynamics of the motion of magnets with coils. A magnet has to cut across the coils to generate electricity through the wires of the coil. A magnet is a transverse field; electromagnetic energy is in transverse (at right angles). Parallel fields are not electromagnet, but are electrostatic or di-electric.
However, in the video above, only a certain amount of current is being generated from the magnet, whereas most of the motion of the magnet occurs in parallel to the coil, not cutting across the coil. So this is an extremely inefficient generator. The outer coils only act to generate a repulsive magnetic field at a moment, but which must occur from a battery inside the coils, or an electret to really be cute.
In the left image, the very lower left part illustrates a magnet passing over the top of one side of a coil or another. Note that when the magnet moves in parallel to the end of the coil, there will be no current, but there will be a slight amount of electromagnetic current generated as the magnet passes near and leaves, but not very much.
In the left image in the middle section, the magnet cuts across the coil to generate electromagnetic current (electricity).
In the left image in the middle right illustration, As the magnet cuts across one end of the coil, the electromagnetic current through the wire, generated by the magnet and coil's interaction will reverse as it crosses through the center.
These are some basics. I realize that some of you are having trouble understanding how to generate electricity using magnets and a coil of wire.
Some generators will generate current without any moving parts. The Bedini engine will use either a spinning magnet rotor, or not, to be a self-generating system.*
This article is the very basics of electromagnetism. Magneto-electrostatic energy is more advanced, but it's not that difficult to understand. Perhaps in the book, I should start with a step-by-step illustrated discourse which goes from basics to intermediary, to advanced. I realize this website starts at the advanced level though, and doesn't really cover a lot of simple basic concepts.
When dealing with electromagnetic field collapse (which occurs at the speed of light all through the coil, which is what makes a high volt spark), that is more of an intermediate level of understanding, although it is just that simple. Unfortunately most college-educated engineers with an associate or bachelor's degree still don't even understand that. The spark collapse (electromagnetic field collapse) is the basis for magneto-electrostatic current, however.
This too needs a correcting remark: An electromagnetic field will collapse at the speed of light, however it can collapse more slowly as in the case of a simple Bedini motor due to resistance. In a free-flowing circuit, a magnetic collapse can encounter resistance electromagnetically as well which slows down its collapse.
So here's the verdict:
The magnetic reed switch works in the presence of a magnetic field, either from the coils or from the rotating magnets. Notice when the video starts, the magnets are slightly oscillating back and forth. This shows that the coils are powered already, and that there is an alike magnetic field that is attracting the two doughnut magnets.
He has to move the magnetic reed switch away from the coils, otherwise the coils will keep the switch turned on.
When the round magnets pass over the magnetic reed switch, is when the LED lights up. He stops the machine and starts it back up, using the pull of the electromagnets to kick it into spin, instead of hand-spinning it. So the coils are charged. The magnetic reed switch breaks the circuit, otherwise without it, the spinning magnets would slow down over time.
The LED is wired at one end to a coil, and at the other end to the switch, and a coil is wired to the switch too, and this carries over to the other side. The other end of the coil is wired to something, either to the other coil, or to a battery. If wired to the other coil, then the outer coil would only activate inductively, and it's pulsing motion of being turned on and off would light the LED.
He must have two coil windings involved, the inside coil connected straight to the electrets or batteries hidden inside the coils, and the outer coil is connected as just stated, to the diodes and to the magnetic reed switch.
Scenario 1: As the outer coils collapse, it applies an opposite field to the inner coils, canceling the electromagnetic field in the two coils, allowing the spinning magnet to not be opposed in its motions so the spinning magnet is either pushed along or pulled along, and the field shut off in timing, similar to how a Bedini flywheel works. The coils' electromagnetic field must be turned off, or otherwise phased out to prevent the spinning magnets from being pulled back as it passes by, so that the net energy is a slight acceleration.
So how do the LEDs light up?
The outer coils are powered inductively from the inner coils, but there has to be a change of motion involved for the LED to light up, because once there is no change of motion, there is no current flowing, inductively.
That is how induction works in electromagnetic coils.
If the LED were connected straight to the batteries inside the coils, it would always be lit. But, since induction is involved, then there must be movement involved. The movement is involved in the filling of the outer coils and the collapse of the outer coils, which creates a sine wave in a current.
Scenario 2: If the LED is being lit due to the filling of the outside coils, inducing the electromagnetic field to form, filling more space, causing movement of electrical flow, lighting up the LED, then as the spinning magnets move past the switch, the outer field collapses and weakens the inner coil field, allowing the magnet to approach the next coil. However, since the coil attracts the magnet, then the coil fields must be weakened as the magnet moves past the coil, instead of as the spinning magnet approaches the coil.
So then the LED is being lit due to the change of motion of the collapse of the electromagnetic field as the switch is broken, and the charge in the coil is rapidly depleted, back flowing through the LED, lighting it, and weakening the inner coil. So when the LED lights up, the electromagnetic field generated by the coils are at their most weakened state, allowing the spinning magnets to move unhindered. So the moving magnet is always being pulled along, instead of pushed along.
The LED blocks the current flowing in one way, allowing the current to flow in the other way. An LED, as a diode, only allows current to flow in one direction, as per a diode's function.
In order for the magnets to spin the opposite way, the switch has to be moved to the opposite coil.
Now here is where things get interesting. It would appear that the inner coil AND the outer coil is BOTH connected to a battery, but not to each other. So when the outer coil is charged, in one way, it forms an opposing electromagnetic field that cancels out the inner coil, so the net electromagnetic field is zero, allowing the spinning magnet to spin without being pulled back to the coil.
When the magnetic switch is activated it completes the circuit, the LED lights, and the fields from the coils drop to zero, which turns the LED off just as quickly as it were turned on.
Therefore the electromagnetic collapse in the outer coil, in the same polarity as the inner coil, quickly brings the field back up, but by then the spinning magnet has already passed out of range, and has enough inertia to continue its path unhindered, and is pulled to the other electromagnet.
We have multiple cases going on here involving the collapse of the outer field either weakening the overall field, or strengthening it, and the formation of the field in the outer coil either weakening the overall field, or strengthening it.
The LED MUST be turned on when power is connected; it cannot turn on due to a collapse, because the circuit would be broken, and the LED would not even light up.
This one is a good puzzle.
The simple mechanics of this:
The magnet is attracted to the coil. When the magnet moves past the coil, the magnetic reed switch is activated, the outer coil is powered, lights the LED, and then the electromagnetic field in the coils drop to zero, turning off the LED, and allowing the spinning magnets to move forward without resistance, being attracted to the next coil, then when the magnets move past that, the switch is activated, pulsing the LED and phasing the electromagnetic field generated by the coils to zero.
As the magnet moves past the magnetic reed switch, the fields in the coils become active again, attracting the magnet to the next coil where the cycle continues.
The easiest way to do this is to fill the inside of each coil with electret material, so that this machine will run indefinitely. Regardless, the coils hold inside them a battery, and the coils are double-coils in kind of a reverse-Bedini setup.
To figure out the wiring, it is best to wire it as it needs to work, and then find a way to hide the wires, which would be easier to do than to figure out the hidden wiring. The visible wiring must be figured out through experimentation, and then it can be realized how to hide the wires.
