A coil is wrapped with 125 turns of wire on the perimeter of a circular frame (of radius. Each turn has the same area, equal to that of the frame. Eld is directed perpendicular to the plane of the coil. This eld changes at a constant rate from 28 mt to 49 mt in 22 ms. B z ~b d~a = b a. The initial angle between the normal to the plane of the circular loop and the magnetic. F = 39 + 180 = 141 . From faraday"s law e = n solenoid the average emf is d b dt for a. = (29. 7 turn) (74 t) (0. 66 m)2. A magnetic eld of 0. 0913 t exists in the re- gion enclosed by a solenoid that has 510 turns and a diameter of 9. 41 cm.
