Task 316450.

Of an aluminum wire whose cross-sectional area is 1 mm ^ 2, a ring with a radius of 10 mm is made. Perpendicular to the plane of the ring in 0.01 s include a magnetic field, in which the induction is 1 T. Find the average value of the induction current that appears during this time in the ring. The specific resistance of aluminum is 2.8 * 10 ^ -8 Ohm * m.
