Induction via Infinite sheet of Current

AI Thread Summary
Inducing a unidirectional electric field outside an infinite sheet carrying current is the main focus of the discussion. The idea proposed involves changing the current in a sawtooth pattern to achieve this effect, as it would theoretically prevent the reversal of the field seen with sine wave forms. However, it is noted that the flyback portion of the sawtooth generates a brief high amplitude pulse of induced field, complicating the goal of achieving unidirectional induction. Ultimately, the consensus is that unidirectional induction cannot be realized with this method. The discussion highlights the challenges in manipulating electric fields through current variations.

My thoughts are concerning an infinite sheet carrying current in a direction. I wish to induce a unidirectional electric field outside of the sheet via induction.

My ideas were that if the current was changed linearly in a sawtooth fashion, then I would achieve the induced electric field in only one direction. I was thinking that since the only decrease in current would occur without a change in time, then the reversal of the field, like with a sine wave form, would be eliminated.

Any help would be greatly appreciated on this!

The flyback part of the sawtooth creates a brief very high amplitude pulse of induced field. You cannot obtain unidirectional induction.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
