A 2-turn planer loop of flexible wire is placed inside a long solenoid of n turns per meter that canes a constant current I, The area A of tire loop is changed by pulling on its sides while ensuring that tire plane of the loop always remains perpendicular to tire axis of the solenoid. If n = 500 turns per meter, Io = 20A, and A = 20 cm² , what is the emf induced in the loop when dA/dt = 100 ?

An inductor consists of 100 turns of wire tightly wound about an insulating core. It is attached to a power supply and when the current through it is increased from 0 to 5 A in 3, s an induced emf of 5 V is measured. Find the inductance of this device and the magnetic flux and the energy stored in the magnetic field when the current is held steady at 5 A.

Coil A is a large 900 turn circular coil of radius 46 cm. Circular coil B has 10 turns, a radius of 4 cm and is located L=42 cm from coil A along the same axis. The planes of the two coils are parallel. If the current in coil A varies with time according to I=12t3−20t2−1, where I is in amps and t is in s, find the magnitude of the EMF induced in coil B at time t=6 s. Select all the statements that are true. Select "None of the above" if none of them are true.A. If we increase the distance between the coils, the mutual inductance will decrease.B. If the permittivity of the region where the coils are located is increased, the mutual inductance increases proportionately. Note that 'permittivity' refers to ϵ or ϵ0.C. If the current is increased, the mutual inductance increases.D. In the first part, if we had calculated the field due to coil B in the region of coil A, rather than the other way around, we would have found no difference in the calculated mutual inductance.E. If we rotated…
