Question

Problem 5b

Answer 1

Given information

Given, the north pole of a thin flat magnet moves on a table toward a loop also on the table, and the magnet is four times thicker than the wire loop. We are asked in what direction the current is induced in the loop.

Step-by-step explanation

Step 1.

We can find the direction of the current in a wire if the direction of the magnetic field is already known using the right-hand rule. Point your thumb in the direction of the magnetic field and curl your fingers. The circular direction of your fingers tells you the direction of the current that creates the magnetic field.
