Question

Problem 5a

Answer 1

Given information

Given that the north pole of a thin flat magnet moves on a table toward a loop also on the table and the magnet is the same thickness as the wire. We are asked in what direction the current is induced in the loop.

Step-by-step explanation

Step 1.

Lenz’s law states that the direction of an induced emf is such that it will always oppose the change that is causing it. That is; an induced current will always oppose the motion or change which started the induced current in the first place.
