Problem 4CQ

Problem 4CQ

Noting that the magnetic field lines of a bar magnet resemble the electric field lines of a pair of equal and opposite charges, do you expect the magnetic field to rapidly decrease in strength with distance from the magnet? Is this consistent with your experience with magnets?

Step-by-Step Solution:
Step 1 of 3

Solution 4CQ

The magnetic field lines are closely spaced near the magnet and the separation between the field lines increases as the distance from the magnet increases.

Yes, it is expected that there will be a rapid decrease in the strength of the magnetic field with the increase in distance from magnet as density of lines of force is directly proportional to the intensity of field’s magnitude in that region. With distance the density of field lines decreases. Hence, the strength of field decreases with distance from the magnet.

This is also consistent with the observation during playing or working with magnets.
