Self induction:

  • The self inductance is defined as the property by virtue of which coil opposes any change in the current flowing through it.
  • Due to this self inductance, when the current in the coil is increased, the self induced EMF in it will oppose this increase by acting in the direction opposite to that of the applied EMF.
  • Similarly, if the current in the coil is decreased, he self induced EMF will tend to keep the current at its original value by acting in the same direction as the applied EMF.
  • Thus, any change in the current  through the coil is opposed due to its self inductance.
  • Hence, self-inductance is sometimes analogously called electrical inertia or electromagnetic inertia.
