Задача 30453.

Ring coil radius R = 3,4 cm, made of copper wire, is located in a uniform magnetic field with induction B = 2 mT. The plane of the coil is perpendicular to the lines of magnetic induction. Revolution without prompting from his plane turned into a figure eight, consisting of two equal rings. What is the charge will take place at the same time on the wire? Cross-sectional area of the wire S = 0,8 mm ^ 2.
