How to smoke Lorentz

[dieter]

MarkE,


First if all, there's no reason to open a champagne bottle and celebrate a party, only because I was wrong.  At least I have the balls to confess my mistake. I have never seen such a behaviour of a PM before, insofar it is quite extraordinary.


Second, I do not agree with your last posting. "My" iron wire is a coil, and any coil can cause a bfield when a current is induced. whether this bfield is attracting or repellung the inducing PM is a matter of the winding, CW or CCW. Therefor, any induced coil can be built in a supportive and in a anti-supportive way. This however may not be enough to overcome the lorentz force, but nevertheless, it makes sense to me.
Contrairy to my observations of the micro wave oven PM Asymmetry, the potentially supportive force of a coil (no matter if copper or iron) will be reversed, depending on whether the coil is moving closer or moving further away from the magnet.


Basicly, my thesis persists, even if my observation was caused by said PM  (which is a yet to be investigated anomaly IMHO)

Unfort. I cannot edit the earlier posts in this thread, so I have to make this clear:


I was totally out of my mind when I wrote that. Of course it is not true that the windung direction only causes attraction vs repulsion... Lenz's law makes clear, it is the opposite.


Sorry folks for posting rubbish, but that magnet used to confuse me quite a lot, ...

Whether a straight, twisted, curled, zig-zagged or any shape you like, a wire carrying a current or not does not form a magnetic monopole.

@dieter

I'll say this much,  the magnetic force around a SINGLE DC current carrying wire
does differ significantly from the force around a permanent magnet or a coil of wire.

The force circulates in one direction only.   It may be that it spirals as well.
This does not I think,  constitute a magnetic monopole. But I think it is still worth pondering.

Thanks Floor, actually I knew that already, It gets more complicated when the coil is made of iron, as the iron will redirect the b-field to flow in parallel with the current, if the insulation acts as an airgap. At least I guess so...
