viii In the middle of a long solenoid there is a coaxial ring of square cross section made of conducting material with resistivity p The thickness of the ring is equal to h its inside and outside radii are equal to a and b respectively Find the current induced in the ring if the magnetic induction produced by the solenoid varies with time as B Bt where is a constant h b a 4p
