Question

Explain self inductance and mutual inductance

Answer 1

Self inductance is defined as the 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 a voltage in the same circuit. Therefore, the voltage is self-induced.

Mutual inductance is where the magnetic field generated by a coil of wire induces voltage in an adjacent coil of wire. A transformer is a device constructed of two or more coils in close proximity to each other, with the express purpose of creating a condition of mutual inductance between the coils.

Hope it helped u..:-)

Answer 2

MUTUAL INDUCTION- consider two coils of wire kept side by side. When the strength or direction of the current in one coil changes the magnetic flux around it changes. As a result an emf is induced in the secondary coil . This phenomenon is the mutual induction.

SELF INDUCTION- The change in the magnetic flux due to the flow of an AC in a solenoid will generate a back emf in a direction opposite to that applied to it. This phenomenon is known as self induction .
