Question

what is self induction write the unit of self induction derive an expression for energy stored in current carring coil​

Answer 1

Answer:

the expression for the coefficient of self-inductance is μ0n2Al. Note The flux through one solenoid coil is ϕ=B×A where the area of the cross section of each turn is A. For the n number of turns then the total magnetic flux is ϕ=n×B×A. The magnetic field is uniform inside the solution.
