Chapter 7.1, Problem 1R

To determine

To explain: A magnet exerts a force on another magnet when the two magnets are not in contact.

Explanation of Solution

Introduction:

A magnet is an object that is capable of attracting other magnets or magnetic materials by producing a magnetic field.

A space around a magnet where it can attract other magnets or magnetic materials is called a magnetic field. Every magnet possesses a magnetic field. Due to this property, it can attract other magnets or magnetic materials even when not in contact. But it is necessary that for a magnet to be attracted to another magnet, it is within its magnetic field.

Conclusion:

A magnet exerts a force on another magnet when the two magnets are not in contact due to its magnetic field.
