Chapter 36, Problem 7A

To determine

To Explain: Some pieces of iron behave like a magnet and some do not.

Explanation of Solution

Introduction:

The few pieces of iron don’t behave like a magnet because the domains are not aligned in one direction.

Generally, in normal condition, the pieces of iron or metal behave like a magnet as the domains are aligned randomly. Every domain in the magnet piece has atoms aligned in a large number.

On the other hand, some pieces behave as a magnet because their domains are all aligned in a specific direction.

Conclusion:

The few pieces of iron don’t behave like a magnet because the domains don’t have a particular alignment.
