Chapter 36, Problem 4A

To determine

To explain: all atoms are not tiny magnets.

Explanation of Solution

Introduction:

All atoms are not tiny magnets because electrons spinning in opposite directions magnetism of each other.

Magnetism is the force exerted by magnetic particles which can be attractive or repulsive. It is caused due to movement of electric charges. The atom of each substance has electrons carrying negative charges. These electrons spin about the nucleus. Their movement generates an electric current and movement of current produces magnetism.

In many substances, equal number of electrons spin in opposite directions to each other and cancelling the magnetism. Thus, all atoms do not behave like tiny magnets.

Conclusion:

Thus, all atoms are not magnetic.
