Magnet Myths and Misconceptions

[MileHigh]

Well Chris, your audience on your thread are asking for build details and test details for your alleged over unity transformer.  You should know this from the replication process that has been going on for years on the forums.  From what I could see there were no specifics in your docs and video clips.

It's going to be a real uphill grind if you expect the replicators to do it all themselves.

The problem I have with this theory is that a magnetic source will induce an opposite magnetic field in piece of iron ie Magnetic Induction.

Say what?  Where do you get that idea?  A magnetic field no more induces an opposite magnetic field in soft iron than a voltage induces an opposite charge in a copper wire.

The external field aligns the domains of the iron producing a second opposite magnetic field which then couples to the external one.

No, the domains in the soft iron align to the original magnetic field.

Thus it would seem this is not a lower resistance path it is a second induced magnetic field coupling to the external one.


If we think about it it would seem to be a simple reversed variation of Lenz law, the source always magnetically induces an opposite polarity in the iron however in this case it does not always oppose as in Lenz Law but always attracts. The phenomena are very similar however one relates to Electromagnetic induction and the other Magnetic induction which also relates closely to Electrostatic induction.

Trying to reason out a behavior that doesn't exist is pointless.

If we have a charged sphere is another neutral sphere nearby a path of lower resistance? Well no, the charged spheres external field produces a charge separation in the neutral sphere producing an opposite polarity E field which is attracted to the first charged sphere. No field lines or flow or low resistance paths are required to explain the phenomena, it is a field related phenomena.

If you have a charged sphere and introduce a conductive uncharged sphere, then the electric field does redistribute, aligning the second sphere to the field of the first:

++++++++++++++++++++++   
+++++++ Sphere 1  +++++++  decreasing positive field with distance
++++++++++++++++++++++


++++++++++++++++++++++                     ------              ++++
+++++++ Sphere 1  +++++++                      -----Sphere2 ++++
++++++++++++++++++++++                     -----               ++++

I think you wanted to write "opposite pole"

The external field aligns the domains of the iron producing a second opposite magnetic field ...

I think you wanted to write "second opposite pole"

Yes, but when this external magnetic field is removed, then something unaligns the domains.
What do you call that "something" ?

NoBull,
       I've often wondered about this with solenoids etc., soft iron is used and this doesn't
retain magnetism well, also perhaps the material itself isn't really magnetised but is
just concentrating the field.
