Chapter 24, Problem 45A

To determine

To Explain: The magnetic field inside the loop is stronger than outside it.

Explanation of Solution

Introduction:

A wire carrying current generates a magnetic field around it. The magnetic field lines are concentric circles around the wire.

When a current-carrying wire is bent into a loop, the field lines inside the loop crowd up making the strength of the field stronger as against outside of the loop.

Conclusion:

Thus, the field lines crowd inside the loop and make the field stronger.
