Chapter 9, Problem 1RCQ

How does the range of refrigerator magnets differ from that of common bar magnets?

To determine

How does the refrigerator magnets differ from that of common magnets.

Explanation of Solution

Every magnet is having two poles. North Pole and South Pole. The magnetic force can attract and repel. The magnetic force is depending up on the distance between the magnets.

The refrigerator magnets are having short range compared to the common magnets.

The refrigerator magnets have alternating North Pole and South Pole narrow strips. Unlike the common magnets, the north and South Pole cancels in a short range. So, the refrigerator magnets have short range compared to the common magnets.

Conclusion:

The refrigerator magnets are having short range compared to the common magnets.
