Induced current with standing magnetic field

Click For Summary
SUMMARY

The discussion centers on the principles of electromagnetic induction, specifically addressing the scenario of inducing current in a wire loop when a bar magnet is moved through it in the presence of a stronger, static magnetic field. It is confirmed that the strength of the external magnetic field does not negate the induction of current; rather, it is the change in magnetic flux that is crucial. This principle is foundational in understanding how electromagnetic induction operates regardless of the relative strengths of the magnetic fields involved.

Hi there,

When you have a loop of wire and you move a bar magnet through it, you induce a current in the wire.

What if you were in a room where there was a magnetic field (not moving) that was stronger than the magnetic field produced by the magnet? If you moved the magnet through the loop in the presence of a magnetic field stronger than that generated by the bar magnet, would a current still be induced in the loop?

Hi Northprairieman! :smile:

Yup! only the change matters, not the proportion. :wink:
