Question

Where is the magnetic field of a bar magnet the strongest?

A.
at the north and south poles

B.
between the north and south poles

C.
next to the south pole

D.
in the middle of the magnet

Answer 1

The correct answer is A. The magnetic field is strongest at the north pole and the south pole of a bar magnet. At the poles, the magnetic field is equally strong while the force is weaker at the middle of the bar. The field lines are closely packed at each pole and it gets wider as the lines get further from the pole.
