Question

define magnetism , and pole strength​

Answer 1

Answer:

Magnetism is a physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.

Pole strength is the measure of amount of force exerted by one of the poles of a magnet to a pole of other magnet. The force can be attraction or repulsion.

Answer 2

Explanation:

Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.

Definition of pole strength. : a quantity corresponding to the amount of magnetic flux emanating from a given magnetic pole and expressed in terms of the unit magnetic pole.
