Chapter 36, Problem 6A

What is a magnetic domain?

To determine

To Explain: Magnetic domain.

Explanation of Solution

Introduction:

A region within magnetic material that has magnetization in a uniform direction, is called a magnetic domain.

Considering an demagnetized object, like a piece of metal, all the magnetic domains are randomly oriented. But when the metal becomes magnetized, all magnetic domains line up and point in the same direction. Hence, the metal acts like a magnet. The metal would quickly become demagnetized when its magnetic domains restore to random order.

Conclusion:

A region within magnetic material that has magnetization in a uniform or similar direction, is called a magnetic domain.
