Why will there be no induced current?

Click For Summary

Discussion Overview

The discussion centers around the question of why there will not be an induced current in a magnetic field that is parallel to a current-carrying wire. The scope includes conceptual understanding of electromagnetic induction and the conditions necessary for inducing current.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions the conditions under which induced current occurs, specifically noting that if no field lines cross an enclosed area, there is no changing field and thus no voltage induced.
  • Another participant asserts that current cannot be induced in a field, emphasizing that a conductor is necessary for current to flow.
  • Some participants challenge the relevance of provided diagrams, suggesting they do not pertain to the question of current induced into a field.

Areas of Agreement / Disagreement

Participants express differing views on the conditions required for induced current, with some asserting that a changing field is necessary while others emphasize the need for a conductor. The discussion remains unresolved regarding the specifics of the question posed.

Contextual Notes

There are limitations in the discussion regarding the definitions of terms like "field" and "current," as well as the assumptions about the nature of the magnetic field and its interaction with conductors.

Bump!
 
Will you please post the reference, textbook, paper, or whatever that is the source of your question?

Current cannot be induced in a field. Current needs some conductor like copper or ionized gas in order to flow.

those pics are not referring to current induced into a field


and as bobby said ... it cannot be, so what really is your question ?

If no field lines cross (i.e., cut through) the enclosed area, there is no changing field. If there is no changing field, no voltage is being induced.
