Self-inductance is the voltage produced by the changing of the electric current through a circuit that contains inductance, which opposes the change in ... more
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the ... more
The magnetic energy stored by a coil carrying a current is given by one half of the inductance of the coil times the square of the current
