We know from everyday experience that magnets attract or repel each other, depending on the relative position between them. We can understand this attraction/repulsion by imagining magnetic...

Unlike other interactions, the forces between two moving charges have certain peculiarities: they are not equal in module and do not have the same direction. Be careful, do not attempt to make...

An experiment conducted by Oersted showed that an electric current produces magnetic effects. The movement of electrical charges gives rise to magnetic fields, and hence, magnetic interaction.

A variable magnetic field induces an electric field and vice versa.
