Question

Define self inductance of a solenoid and write its si unit

Answer 1

Answer:

The self inductance is defined on the magnetic flux linked with the coil when unit current flows through it. The self inductance is defined as the emf induced in the coil, when the rate of change of current in the coil is 1 ampere/second. The SI unit of self inductance is henry (H).

Answer 2

Answer:

$\mathtt \blue{ \xcancel{{d B = \frac { M _ { 0 } n d x I a ^ { 2 } } { 2 [ ( r - x ) ^ { 2 } + a ^ { 2 } ] ^ { 3 / 2 } }}}}$
