96. In a uniform magnetic field with induction B = 20 mT placed superconducting ring of radius r = 50 cm c inductance L = 1,5 Mr. Ring plane parallel to the vector of magnetic induction, and the initial current in the annulus is absent. Ring turned by an angle α = 90 ° so that its plane was perpendicular to the field lines. Determine the current I in the ring after the turn and perfect when you turn the job A.
