A long, straight conductor passes through the center of a metal ring, perpendicular to its plane. If the current in the conductor increases, is a current induced in the ring? Explain.

Homework Answers

Answer #1

The answer is No.

According to Faraday's induction law the answer is No,and it doesn't depend on the form of the current ( ac or dc).

Because the current is induced since the net flux enclosed by the ring will not change

The fact is that no matter how the current in the wire ( straightconductor ) changes the magnetic flux in the metal ring does notchange. The magnetic field created by the wire is parallel to theplane that the ring lies in, therefore the field lines do not enterthe ring ( do not come out or go in the surface of the ring ). Sono current would be induced in the ring.
