A long solenoid of 10 turns / cm has a small loop of area 1 sq. cm placed inside with the normal of the loop parallel to the axis. Calculate the placed across the small loop if the current in the solenoid is changed from 1 A to 2 A in 0 .1 s, during the duration of this change.

A long solenoid with 15 turns per cm has a small loop of area 2.0 cm^2 placed inside the solenoid normal to its axis. If the current carried by the solenoid changes steadily from 2.0 A to 4.0 A in 0.1 s, what is the induced emf in the loop while the current is changing?

A pair of adjacent coils has a mutual inductance of 1.5 H. If the current in one coil changes from 0 to 20 A in 0.5 s, what is the change of flux linkage with the other coil?

A rectangular wire loop of sides 8 cm and 2 cm with a small cut is moving out of a region of uniform magnetic field of magnitude 0.3T directed normal to the loop. What is the emf developed across the cut if the velocity of the loop is 1 cm s^-1 in a direction normal to the shorter side of the loop? For how long does the induced voltage last ?

A rectangular wire loop of sides 8 cm and 2 cm with a small cut is moving out of a region of uniform magnetic field of magnitude 0.3 T directed normal to the loop. What is the emf developed across the cut if the velociy of the loop is 1 cm s^-1 in a direction normal to the: longer side of the loop? for how long does the induced voltage last in each case?

A rectangular wire loop of sides 8 cm and 2 cm with a small cut is moving out of a region of uniform magnetic field of magnitude 0.3T directed normal to the loop. What is the emf developed across the cut if the velocity of the loop is 1 cm s^-1 in a direction normal to the longer side? For how long does the induced voltage last?

A rectangular loop of sides 8 cm and 2 cm with a small cut is moving out of a region of uniform magnetic field of magntude 0.3 T directed normal to the loop. What is the voltage developed acros the cut, if the velocity of the loop is 1 cms^-1 in a diretion normal to the shorter side of the loop. For how long does the induced voltage last in each case?

A long solenoid of length 1 m, cross sectional area 10 cm^2 , having 1000 turns has wound about its centre a small coil of 20 turns. Compute the mutual inductance of the two circuits. What is e.m.f. in the coil when the current in the solenoid chanages at the rate of 10 As^-1 ?
