Simple free energy.
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.
As the magnet passes by the coil, it induces an electromagnetic field into the coil. The magnet induces an electromagnetic current, which in passing through the wire creates a magnetic field.
The motor speeds up until it reaches an equilibrium.

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.
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 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.

Free energy is nice. That is a rather unusual way to generate electric current, or electromagnetic fields. How does a coil of wire and a magnet work to generate electricity and electromagnetic fields? The below is an illustration.
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.
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.*
More is discussed on the Construction blog about this .. but the purpose of this article is to illustrate the relationship between two coils, to note the geometry of using two as one, as seen in the video link.
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.
The article below introduces an advanced Tesla generator which is the basis for a primary engine system and auxiliary engine system of the warp drive. I realize there's a huge gap from basic electromagnetism to warp drive. The article below also deals with proprietary technology, which is more rarified and less explained. Out of necessity though, it's full understanding is compartmentalized throughout this website, where each page covers a portion of it, but it still requires the reader to learn through his/her own experimentation.
It is frustrating to me that the average reader does not understand the basics, and only has generally an intermediate level of engineering physics knowledge, and maybe some quantum physics under his/her belt. Some of you have advanced knowledge, but are not familiar with Tesla engineering physics at all, even if you may have a Ph.D. in quantum mechanics. Many quantum physics professors do not even believe in free energy, and have never even seen a Bedini engine, and have no idea how a Tesla coil works.
It does not take advanced calculus just to start to understand free energy, which is way more simple than you may think, as the link above shows.
