The self inductance of a straight conductor is zero.

The self inductance of a toroid is :-

Obtain an expression for the self inductance of a straight solenoid of length l and radius r (l > > r).

Self Induction

The self inductance of a coil is a measure of

Unit of self inductance is

The unit of self inductance of a coil is

Self inductance || L-R Circuit

In the diagram I_(1),I_(2) are the strength of the currents in the loop and straight conductors respectively OA=AB=R. the net magnetic field at the centre O is zero . Then the ratio of the currents in the loop and the straight conductor is

Distinguish between self induciton and Self induction. Give two factors on which self inductance of an air cored coil depends ?
