Electric generators induce an emf by rotating a coil in a magnetic field. Electromotive force, also called Emf, is the voltage developed by any source of ... more

Light as one type of electromagnetic (EM) wave, is a transverse wave, consisting of varying electric and magnetic fields that oscillate perpendicular to ... more

The drift velocity is the average velocity that a particle, such as an electron, attains in a material due to an electric field. It can also be referred to ... more

The magnetic field generated by the electric current, around a straight wire, is related to the electric current and the distance “r” from the ... more

Permeability is the measure of the ability of a material to support the formation of a magnetic field within itself. In other words, it is the degree of ... more

A magnetic dipole is a closed circulation of electric current. A simple example of this is a single loop of wire with some constant current through ... more
