Chapter 36, Problem 19A

To determine

To Explain: The probable cause of the earth’s magnetic field according to most geophysicists

Explanation of Solution

Introduction:

The current which is present in the molten interior of the earth is responsible for the probable cause of earth’s magnetic field.

The magnetic field is created due to the rotating electric current. But in the case of earth, the liquid metals flow in the outer core of the planet which is responsible for the production of electric current. So, the magnetic field is generated by these electric currents due to the rotation of the earth about its axis.
