Where on a magnet is the magnetic force strongest?
|
|
at the north pole only
|
|
|
at either pole
|
|
|
halfway between the poles
|
|
|
the force is equally strong everywhere
|
Explanation:
Detailed explanation-1: -The two ends of the bar magnet exert the maximum magnetic force. It is equally strong at the north pole and the south pole. The force exerted by the middle of the magnet is weaker.
Detailed explanation-2: -THE MAGNETIC FORCE IS CONCENTRATED AT THE TWO ENDS OR POLES OF A MAGNET. The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
Detailed explanation-3: -The magnetic field is strongest at the poles as the field lines are very close to each other near the poles.
