The “Light Emitting Diode” or LED as it is more commonly called, is basically just a specialized type of diode as they have very similar electrical characteristics to a PN junction diode. . 1. Recap. When a current-carrying . semiconductor or metal. is kept in a magnetic field, the charge carriers of the . semiconductor. experience a force in a direction perpendicular to both the magnetic field and the current. At equilibrium, a voltage appears at the .
