The magnetic potential energy stored in a certain inductor is 25 mJ, when the current in the inductor is 60 mA. This inductor is of inductance

The emf E of a source varies with time. It sends a current I through a coil of self-inductance L connected to it. What is the instantaneous effective emf of the circuit?

A fully charged capacitor C with initial charge q_0 is connected to a coil of self-inductance L at t=0. The time at which the energy is stored equally between the electric and the magnetic field is

If two physical quantities a and b are related by the equation a= kb where k is dimensionless constant, then the principle of dimensional homogeneity demands that a and b have the same dimension. However the proportionality constant k cannot be determined by dimensional analysis only. It may at most be written that a prop b if a and b are of the same dimension. A coil of inductance L stores an amount of energy (1)/(2)Ll^(2) when a current I passes through it. The dimension of L is

How will the magnetic field intensity, at the centre of a circular coil carrying currents, change if the current through the coil is doubled and radius of the coil is halved ?
