INERTIA of electricity:Self induction is that phenomenon in which a change in electric current in a coil produces an induced emf in the coil itself. Now, it is also known as inertia of electricity as for if we were to change electric current through a current carrying coil it will tend to oppose any further change in its emf.

Electromagnetic Induction :Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. Michael Faraday is GENERALLY credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction.

Self Induction:Self INDUCTANCE is defined as the induction of a VOLTAGE in a current-carrying wire when the current in the wire itself is changing.

Moment of Inertia: a quantity expressing a body's tendency to resist angular acceleration, which is the sum of the products of the mass of each particle in the body with the SQUARE of its distance from the axis of rotation.
