Question

what is self induction

Answer 1

Self inductance is defined as the induction of a voltage in a current-carrying wire when the current in the wire itself is changing. In the case of self-inductance, the magnetic field created by a changing current in the circuit itself induces a voltage in the same circuit. Therefore, the voltage is self-induced

Answer 2

induction of an electromotive force in a circuit by a varying current in the same circuit
