Magnetic field change with no drag?

"Exotic material keeps frustrated electrons flipping
Magnetic, temperature and structural studies have yielded new insights on the material sodium iridium oxide"

"As electrons spin, they generate a magnetic field which can point ?up? or ?down?. Within solid materials, an electron will generally try to adopt the opposite spin orientation to its neighbor, just as two bar magnets will flip around so that north and south poles line up next to each other....But in certain materials, the arrangement of atoms can make it impossible for the electrons to line up with all of their neighbors, and they are said to be ?frustrated?."

Amazing how scientific discoveries seem to continue to escalate - the more you know - the more you learn etc.  And to think we only know a portion of the 5% of the observable universe (half maybe? ha - not even?)  What will the other 95% (dark matter/energy etc) bring us?  And how many "laws" will we be adding to the list of ones proved wrong in the past?!?

In total though - to generate EMF requires the introduction of a magnetic field.  The current in the coil will create its own magnetic field.  Thus - if we try in any way to reduce the effect of ANY of the fields (to reduce drag) we will correspondingly reduce EMF?

 Could a pulsed coil's EMF, used to fire a magnet, be used to power another coil to fire another magnet and that coils EMF to power the next?

Is the EMF created at the same time as the coil is powered or right after the power is shut off?

And if it is created after the power is shut off, then couldn't the EMF be used to continue the power flow making it a continuous power flow unlike the pulsed power flow it is being powered by?
