Question
In the figure, a uniform magnetic fieldBis confined to a cylindrical volume of radius0.01m.Bis directed into the plane of the paper and is increasing at a constant rate of ?B/?t =0.900T/s. Calculate the magnitude and direction of the current induced in a circular wire ring of radius 0.16 m and resistance4.5? that encircles the magnetic field region.

Calculate the magnitude and direction of the current induced in a circular wire ring of radius 0.16 m and resistance4.5? that encircles the magnetic field region.Explanation / Answer
the current produced will be in the counter-clockwise direction and the magnitude is given by
i = 0.9*pi*0.01^2/4.5 = 2*10^-5 T
