What is magnetism definition?

A Closer Look: Magnetism is intimately linked with electricity, in that a magnetic field is established whenever electric charges are in motion, as in the flow of electrons in a wire, or the movement of electrons around an atomic nucleus. read more

Basic to magnetism are magnetic fields and their effects on matter, as, for instance, the deflection of moving charges and torques on other magnetic objects. Evidence for the presence of a magnetic field is the magnetic force on charges moving in that field; the force is at right angles to both the field and the velocity of the charge. read more

Magnetism is the phenomenon that arises from the force between objects that produce fields that attract or repel other objects. Magnetism is the phenomenon that arises from the force between objects that produce fields that attract or repel other objects. read more
