Self-Induction

1. Self-induction is the phenomenon of induced emf in the conducting circuit when the current flowing through the circuit.
2. Self-induction is induction of an electromotive force in a circuit by a varying current in the same circuit.

Since self-inductance is associated with the magnetic field produced by a current, any configuration of conductors possesses self-inductance. For example, besides the wire loop, a long, straight wire has self-inductance, as does a coaxial cable. A coaxial cable is most commonly used by the cable television industry and may also be found connecting to your cable modem. Coaxial cables are used due to their ability to transmit electrical signals with minimal distortions. Coaxial cables have two long cylindrical conductors that possess current and a self-inductance that may have undesirable effects.
