Jim,
The south pole scalar is the force that causes the motor/energizer to
rotate, that force is equal to the charging radiant force, no
current. Some have asked about, how do we get motor torque. If you
want torque then you give up the radiant charging. Another words if
you add current to switch the north pole as a motor function you will
lose the radiant charge and you can only have what the normal
reversal of the coil is, in back EMF, that is about 20%. Again if you
use the motor function you will have no radiant energy for charging,
please do not confuse the two functions.
