Question

What is the Definition of self induction​

Answer 1

Answer:

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

Self-inductance Formula

We can derive an expression for the self-inductance of a coil from Faraday's law of electromagnetic induction. VL = −N (dϕ / dt) Where: VL = induced voltage in volts. N = number of turns in the coil.
