Acurrent is induced in a circular loop of radius 1.5 cm between two poles of a horseshoe electromagnet (like that shown in the figure in eddy currents and magnetic damping) when the current in the electromagnet is varied. the magnetic field in the area of the loop is perpendicular to the area and has a uniform magnitude. if the rate of change of magnetic field is 10 t/s, find the magnitude of the induced current if resistance of the loop is 25 ω. report your answer as a positive number in units of ma (milliamps).
