How is self-induction in a coil related to its inductance?

Self-induction in a coil is directly related to its inductance.

Inductance is the property of a coil that opposes any change in the current flowing through it. When the current in a coil changes, it produces a magnetic field that induces an electromotive force (EMF) in the coil itself. This EMF is known as self-induced EMF, and it opposes the change in the current that produced it.

The magnitude of the self-induced EMF is directly proportional to the rate of change of current in the coil. This means that the larger the inductance of the coil, the greater the opposition to any change in current, and hence the larger the self-induced EMF.

The inductance of a coil can be calculated using the formula L = NΦ/I, where L is the inductance in henries, N is the number of turns in the coil, Φ is the magnetic flux through the coil, and I is the current flowing through the coil.

In summary, self-induction in a coil is related to its inductance because the inductance determines the magnitude of the self-induced EMF that opposes any change in current flowing through the coil.
