Induction via Infinite sheet of Current

Click For Summary
SUMMARY

The discussion centers on the induction of a unidirectional electric field from an infinite sheet carrying current. The user proposes using a sawtooth waveform to change the current linearly, aiming to eliminate field reversal associated with sine waveforms. However, it is established that unidirectional induction is not achievable due to the inherent nature of electromagnetic induction, as indicated by the response highlighting the brief high amplitude pulse generated during the flyback phase of the sawtooth waveform.

PREREQUISITES
  • Understanding of electromagnetic induction principles
  • Familiarity with current waveforms, specifically sawtooth and sine waves
  • Knowledge of electric field generation from current-carrying conductors
  • Basic concepts of field directionality in electromagnetism
NEXT STEPS
  • Research the principles of electromagnetic induction in detail
  • Explore the characteristics and applications of sawtooth waveforms in electrical engineering
  • Study the behavior of electric fields generated by different current waveforms
  • Investigate the limitations of induction methods in generating unidirectional fields
USEFUL FOR

Electrical engineers, physicists, and students studying electromagnetism who are interested in the practical applications of current induction and electric field generation.

Brendan Graham
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.
