Definition: Self-inductance or in other words inductance of the coil is defined as the property of the coil due to which it opposes the change of current flowing through it. Inductance is attained by a coil due to the self-induced emf produced in the coil itself by changing the current flowing through it.

Answer 2

it is a defined as a 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 the voltage in the same circuit .therefore the voltage is self induction.
