Will Current Flow Through a Rotating Copper Wire Loop in a Magnetic Field?

Click For Summary
SUMMARY

The discussion centers on the behavior of a copper wire loop subjected to a uniform magnetic field while being rotated about a vertical axis. According to Lenz's Law, an induced current should occur when there is a change in magnetic flux. However, the participants conclude that since the loop transitions from having full magnetic flux to none, there is no induced current during the rotation, as they cannot determine a direction for the current that would counteract the change in flux.

PREREQUISITES
  • Understanding of Lenz's Law
  • Familiarity with magnetic flux concepts
  • Basic knowledge of electromagnetism
  • Ability to analyze rotating systems in magnetic fields
NEXT STEPS

Homework Statement


A copper wire loop is initially at rest in a uniform magnetic field (full flux going through it). Between times t=t1 and t=t1+(delta)t the loop is rotated about a vertical axis as shown (no flux going through it). Will current flow through the wire of the loop during this time interval? If so, indicate the direction of the induced current and explain your reasoning.


Homework Equations


Lenz's Law


The Attempt at a Solution


Well, since the loop goes from having flux to having no flux at all I would have assumed there'd be an induced current. However, I can't seem to find a direction of current that would counteract this change in flux. So in that sense would there be no current induced at all?

Where? It seems you forgot to include the diagram.
