Chapter 36, Problem 45A

Earth’s core is probably composed of iron and nickel, excellent metals foe making permanent magnets. Why is it unlikely that Earth’s core is a permanent magnet?

To determine

To explain: The earth is considered as a permanent magnet

Explanation of Solution

Introduction:

The strongest magnetic field of the earth is passing out from the core of the earth which passed through the earth and enters into space.

Iron and nickel are the excellent metals for making the permanent magnet. The core of earth contains nickel and iron. The earth’s core is so much hot for the individual atom to remain aligned. So, it is unlikely to say that the core of the earth is a permanent magnet.

Conclusion:

The core of the earth is very hot for the iron and nickel are to be magnetic.
