Cоnsider а circulаr lооp of wire. The mаgnetic field strength at the center of the loop is given by the equation B(t) = [2.0 T/s]t, where t is time in seconds. If the induced electric field outside the loop is |E| = 3.4 V/m at a distance of r = 7.0 m from the center of the loop, find the radius R of the loop. Hint: The result of the line integral of the electric field around the path is E*2
