A small circular loop of wire of radius 5.0 cm and resistance R = 9.0 10-4 Ω is centered inside a large circular loop of wire of radius 50 cm (see figure below). The larger loop, which initially carries a current I = 6.5 A, is cut and its current is reduced to zero over a time interval of 1.2 10-6 s. Find the average current in the smaller loop during this time interval. (The magnetic field of the larger...
A loop of wire with radius R lies in the xy-plane and carries a time varying current I(t) I, sin(ot). A smaller loop of wire with radius a lies in the xy-plane at the center of the larger loop.

A square loop of wire with a small resistance is moved with constant speed from a field free region into a region of uniform B field (B is constant in time) and then back into a field free region to the left. The self inductance of the loop is negligible. When entering the field the coil experiences a magnetic force to the left. When leaving the field the coil experiences a magnetic force to the right. Upon entering the field,...
