EXCELLENT POINT! That both must be present....this is getting intensely
interesting....by forcing a SEPARATION so that the two cannot react to
each other....and I like your idea of a wheel..
I always considered electricity the CHILD of magnetism since by cutting
a magnetic field with the crystalline structure of a wire, you induce
current flow and thus electricity.
And we've not even brought in superconductivity where there is NO
ELECTRICITY, ONLY PURE MAGNETIC CURRENT that is REPELLENT to magnetic
fields. Oddly enough, am I wrong, or isn't there NO magnetic field
inherent in superconductors. Here are some InterNet quotes;

So, a superconductor MIRRORS any APPLIED magnetic field to REPEL IT!

I don't understand this comment. DC means direct current and when it
flows through a wire, there is ALWAYS a magnetic field associated with
it as in 'solenoid'.
-------------------
And that brings up another question, it is the MOTION of current through
the wire that creates the magnetic field, so if there is NO MOTION,
there is no CURRENT.
So what gives with magnets, where a magnetic field is present yet there
is no 'motion' as we consider it. Does this mean there is a CURRENT
flowing in magnets??? If so, why can we not tap it except by cutting
the lines of force??? Perhaps David Hudsons comment about resonance
might be a serious key...find ther resonant frequency of a magnet or the
flow of the flux lines and pull energy off by resonance alone.
