Find the energy stored in the magnetic field if current of 5A produces a magnetic flux of `2xx10^(-3)` Wb through a coil of 500 turns.

What will be the self inductance of a coid of 100 turns if a current of 5 A produces a magnetic flux 5xx10^(-5) Wb?

If a current of 4A produces a magnetic flux of 10^(-3) Wb per turn in a coil of 1000 turns, then the self inductance of the coil is

If a change is current of 0.01 A in one coil produces a change in magnetic flux of 2xx10^(-2) Wb in the other coil, then the mututal inductance of the two coils in henry is
