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 loop is approximately constant over the smaller loop.) magnitude direction Correct: Your answer is correct.

A circular loop of wire with radius R is in a uniform magnetic field with magnitude B that points in the positive z-direction. The loop is initially in the xy-plane and carries a constant, unknown current. Flipping the loop over requires you to do positive work (W). Determine the current in the loop.

A circular loop of radius 5.0 cm and resistance 0.4 Ω lays in the horizontal XY plane. A uniform magnetic field is established pointing upwards, that's to say, in the direction of the positive Z axis. At t = 0, the magnitude of the magnetic field is 120 mT, but then it is increasing at a rate of 40 mT/s. Find the induced current in the loop at t = 1 s, and discuss whether its direction is clockwise or...
