List of top Physics Questions on Inductance asked in MET

Find the inductance of a unit length of two parallel wires, each of radius \(a\), whose centres are at distance \(d\) apart and carry equal currents in opposite directions. Neglect the flux within the wire.

Two coils have mutual inductance 0.005 H. The current changes in the first coil according to equation \(I = I_0 \sin \omega t\), where \(I_0 = 10\text{ A}\) and \(\omega = 100\pi\text{ rad/s}\). The maximum value of emf in the second coil is

Current in a coil changes from 5 A to 10 A in 0.2 s. If the coefficient of self-induction is 10 H, then the induced emf is
