A square current carrying loop is changed to a circular loop in time $t_1$. Then

For a current carrying inductor, emf associated is 20mV. Now, current through it changes from 6A to 2A in 2s. The coefficient of mutual inductance is

A solenoid has $2000$ turns wound over a length of $0.30\, m$ . The area of its cross-section is $1.2 ? 10^{-3}\, m^2$. Around its central section, a coil of $300$ turn is wound. If an initial current of $2A$ in the solenoid is reversed in $0.25\, s$, then the emf induced in the coil is

A small coil is introduced between the poles of an electromagnet so that its axis coincides with the magnetic field direction. The number of turns is n and the cross-sectional area of the coil is $A$. When the coil turns through $180^{\circ}$ about its diameter, the charge flowing through the coil is $Q$. The total resistance of the circuit is $R$. What is the magnitude of the magnetic induction?
