Question

magnetic fields
field lines and field strength

1. examine the closely packed field lines in the image. what connection can you make between the number of field lines and the strength of the field?

a. several field lines close together indicate a strong field.
b. several field lines close together indicate a weak field.
c. the number of field lines does not influence the strength of the field.

Explanation:

In magnetic fields, the density of field - lines represents field strength. More closely - packed field lines mean a stronger field.

Answer:

A. Several field lines close together indicate a strong field.
