Homopolar Generators (N-Machine) by Bruce de Palma

Solid connections using a small tie wrap.  And being there wasnt even a jiggle, then the magnets ability to be 'able' to roll on the foil tells me that the foil was most likely having some force pushing it back as the mag pushes forward, except the foil was on a fixed platform so only the mag moved.

Mags

Can you repeat this experiment so the magnet is free to move away from the wire pieces?  The edges of the magnet can produce magnetic storms (vortexes) by motion through space as shown below.


In 1988 Prof Francisco J. Muller completed a series of experiments, substituting Faraday's rotating disk and magnet by a filamentary circuit, one portion of which is immersed in a magnetic field (inside a gap between ceramic magnets) while the other remains outside the magnetic field. (The field is confined within iron plates).  By introducing a capacitive branch he could demonstrate that the induction occurs, indeed, in the wire that moves with the magnet, without need of relative motion. A variation of the experiment in rectilinear fashion makes this anti-relativistic conclusion totally unavoidable, invalidating the recourse to General Relativity. A list of other publications by Muller can be found at the World Science Database.


For the rotational case in Figure 1 there is a potential difference induced between O and R due to the ABSOLUTE ROTATION of the system, in-spite of the absence of relative motion between the magnet and wire.  In Figure 1, all of the velocities are parallel or tangential to the magnetic edges.  For the translational case in Figure 2 there is no induction between O and R.  In figure 2, the B field is the same, the speeds also are similar, and no relative motion exists as in Figure 1. Why the difference?


In Figure 1, all of the velocities are parallel or tangential to the magnetic edges.  In figure 2, most of the velocities have components perpendicular to those edges.  As a result, in Figure 2 the edges of the magnet produce magnetic "storms" by motion through space (an absolute effect) which are equivalent to negative (VxB) effects.  The latter cancels the positive (VxB) fields thus yielding zero net induction.

I can give it a shot.

Will just need to mount the mag at the bottom of a pendulum arm and suspend some contact wires to touch the bottom and top of the mag. Not at the shop at the moment. Maybe tomorrow evening.

Will have to be tried with wires to contact points from different angles. From the sides, front and rear, etc. Many combinations including a wire straight up to the bottom and straight down to the top.

Im still leaning toward the effects to the foil due to the mags filed and currents in the foil.

The wires cant have those effects due to only one path for the currents to go, so the mags field will have minimum effect on the wires as compared to what I have described the foil as having.

I have decided to try my idea on the inverted mag film tests of the foil also. Actually, I am going to do that first. Both tests are easy enough to do.

Will do this after work today. Would be interesting to see if the field in the foil changes around the mag when current flows compared to no current.

My mag film is 4 3/4 by 3 3/4in, so I will make the foil the same size to possibly get a full view of the foil while changing the input contact points of the foil.  Again, I am leaning toward the foil reactions described earlier. The foil provides an odd mix in this being that the currents can flow through the foil as a whole conductor. So the mags field can definitely cause deflections in how that current flows to get to the bottom contact of the magnet.

The new pendulum test will be done with the top connection using a wire to hang it from, then just need to make loose contact with the bottom to see if it moves with the bottom wire at different angles including a vertical connection.

Mags,

You may be partially right.  In your initial experiment, there is more conductive material underneath the magnet than there is above the magnet, and this could cause an unequal breaking force between the top and bottom edges of the magnet, similiar to this video showing how a magnet will find the center of its own way on a conductive path,  https://www.youtube.com/watch?v=d4KKeA3RI98

Please let me know what you think.

Thanks,

Mags,

In the pendulum test, you could also place a conductive material that covers a larger area underneath the magnet that isn't part of the cicuit.  There should be a gap between the magnet and this additional conductive material.


Thanks,
