The bearing motor

[tinman]

Oh...Duh!  I read about the sphere within the sphere but it looked like he was so careful in placing it on the stand like it was in hover position.  I just looked again and...who the heck would pay 140 bucks for that?

OK, now I feel stupid.

Thanks for the explanation Brad.

Lol,all good,as i was wondering the same thing -until i watched the second video lol.

Its possible that placing one mag somewhere on the outer race may not produce an equal offset on all the balls. Try anyway though.  Im thinking one at the end of the shaft, like N or S in and one at the other end of the shaft, trying N then S in. Same poles in, say N in, then the whole shaft will emanate N field.  Then also a N in on one end and S in on the other could be the way to go also.

Then again, it may not help at all. lol   So try as many mag positions as possible as to not miss anything.  If the mags help but self starting doesnt work but seems to bias the rotor more in one direction than the other, then a stronger mag is needed.

Mags

Mag's,MH-anyone.
Im looking at the homopolar motor(the simple 1 battery/magnet combo),and i see a uniform magnetic field around the wire,immersed in a uniform magnetic field around the PM. How dose this create a force in one direction to create the motoring effect?.The battery is only there to create a current flow that creates a magnetic field around the wire-correct?

Yeah, weird stuff.  I wonder if we eliminate the mag, if the wire would spin in either direction, with a little push.

I believe the field of the side of the magnet that is touching the battery is attracted to the battery like a core and that field flowers out from the sides of the battery. Say it is N contacting the battery, then the outside surface of the battery emanates N pole field all around it. So now we have the wire with current flowing wile it is constantly in that N field and the wire moves. Faraday.

Ill try and do some tests as I get time to do so.

Just make a diagram of the homopolar motor and work it out for yourself like I tried a few postings ago for the bearing motor.  Before you tackle the bearing motor you want to be able to explain the homopolar motor and you may as well throw in explaining the aquarium vortex and bubbles business if you want.

All of the basic concepts have already been stated in the past week, so there is no point in repeating them.  It just a question of applying the concepts to the homopolar motor setup.

The one I made was simple.  Just a D cell with a metal screw held onto the bottom via the flux from a neo cylinder which was hanging from the screw.  Just touch the frayed end of a wire from the + on the bat. to the mag. and it spins up very fast.  I never did try to reverse polarity to see if it spun the other way.  I can give that a try.

PS  I should add that I have no idea why this works like it does.
