Chapter 36, Problem 14A

To determine

To explain: The way in which the earth’s magnetic field plays an important role in cosmic ray bombardment.

Explanation of Solution

Introduction:

When cosmic rays are bombarded on the earth, the incoming charged cosmic rays get deflected by the earth’s magnetic field.

The direction in which a moving particle is forced is similar to the direction of the current-carrying wire in a magnetic field in which it is forced. So, the many charged particles which make up cosmic rays are deflected by the earth’s magnetic field.

Conclusion:

Hence, the earth’s magnetic field deflects the coming cosmic rays.
