Inductance is a property of a closed loop and a physical quantity. When the current passes through the coil, a magnetic field is induced in the coil, and the induced magnetic field generates an induced current to resist the current passing through the coil. This current and coil name. It describes the circuit parameters that cause the induced electromotive force effect in this coil or in another coil due to the change of the coil current. Inductance is the general term for self-inductance and mutual inductance. Devices that provide inductance are called inductors.
