Chapter 24, Problem 81A

To determine

To Describe: A experiment to find the poles of a magnet hidden in a fixed position inside a tennis ball.

Explanation of Solution

Introduction:

A magnet is an object that produces its own magnetic field which interacts with external magnetic fields. A magnet has two poles- north and south. Similar poles repel away each other whereas dissimilar poles attract towards each other.

The poles of the magnet inside a ball can be found out by using another magnet whose polarity is known, for e.g. a compass. The north pole of the compass will attract the south pole of the magnet inside the ball and vice versa.
