The Bedini motor was a gift to the open source energy community by John Bedini. While i don't think the system exhibits any type of over unity it certainly does produce a usable transient spike. This magnet spinner uses a simplified bedini circuit
to pulse the coil.
The intermittent attraction and repulsion of the poles causes the magnet to accelerate it's spin.
The magnet is diametrically magnetized having the north and south on the sides (curved edge) rather than the top and bottom.
When the magnet approaches the coil, the coil begins to build a charge. There is a backwards EMF opposing this charge caused by one strand of wire creating a magnetic field at right angles to the current, which starts a current in the next wire and so on. The coil is fighting itself to charge up and so it takes some time for the coil fully charge up. When the magnet passes the coil the field collapses and it does so more quickly than the time it took to charge up due to the lack of a BEMF.
The collapse of this field is akin to a compression of time. It is at this point that a radiant spike is observed in the coil. I have heard many people refer to this as back EMF (BEMF) which i don't believe is correct. The BEMF is what opposes the initial charging of the coil and by the time this measurable spike occurs the BEMF is long gone.
Particle physics working in Minkowski space would dictate that the energy comes from the compression of time. Energy is absorbed in the time domain in compressed form and released in three space uncompressed as longitudinal waves. The quantum theory relating to this dates back to 1985. Tom Bearden explains that every charge and charge dipole accomplishes broken symmetry in both three space and the time domain. There is exactly as much energy in the form of compressed time in the fourth domain that is released as energy in three space in expanded form meaning that the conservation of energy law is not broken and we have discovered the giant negative entropy system of nature.
Whichever theory is correct, the fact is that this transient spike can be measured with an oscilloscope and captured in the circuit with the choice of either feeding it back into the system or charging a battery.

I have created a visual diagram of the circuit instead of a schematic. There are a few important points to keep in mind should you decide to create one for yourself. The magnet needs to spin on a slightly concave surface to prevent it from straying away from or crashing into the coil. Since creating the video below i have found that the coil wrapped around the object that the magnet spins on has little effect. It does have an effect of stabilizing the spinning magnet but the effects are minimal. You can bypass this coil in your circuit.
In my diagram and videos i am using an old pill bottle with a concaved bottom. You can also use a magnifying makeup mirror with a concave surface. The magnet needs to be spun fairly fast in order to trigger the circuit into oscillation. It can be difficult to get the momentum required without having a piece of dowel in the top of the magnet. In other videos i do not use this dowel but it does make it much easier to generate more spin.
The coil is bifilar wound with one gauge being smaller than the other. In my case the smaller guage wire had more wrappings than the larger gauge. I won't go into the details on how to wind a coil except to say that it will go much easier if you first build something to help you. I knocked up a basic coil winding jig from a broken microphone stand and some MDF board. This made the winding much neater and faster than if i wound the whole thing by hand. While the 10K potentiometer is not a necessity it allows you to vary the speed of the spinning magnet by lowering resistance in the circuit. This setup only requires 1.5 volts to run and does not involve any charging of batteries or capturing of transient spikes.
