The Electric Field,sed. The starting point is usually from the experimental investigations carried out in 1785 by Cavendish and Coulomb, who likened the electrostatic field associated with the charge on a body to the gravitational field associated with the mass of a body.

The Electric Field and Materials,ds in the presence of materials. The space in which an electric field exists is usually a dielectric such as air, mica, oil, etc., and the boundaries of this space where charges in the main reside are conductors such as aluminium, copper, etc.

Magnetic Forces and Magnetic Media,t magnetic materials and magnetic circuits play an important part. Our previous discussion has been limited to magnetic effects, mainly in free space, which arise from conduction-type currents. Now, after first considering the mechanical forces exerted upon current-carrying conductors, we shall exam
