A conducting filament containing a small 400 ohm resistor is formed into a square loop on the x-y plane as explained in the previous problem. Find I at t = 2*10^-4 sec if

(a) \(B = 3cos(12000\pi t)a_z T\)

(az is the unit vector in the z-direction, or z hat)

(b) \(B = 200cos(20\pi t)a_x + 0.4cos[\pi (ct - y)]a_z T\)

where c = 3*10^8 m/s. Also, indicate whether the current is flowing clockwise or countercockwise. (ax and az are unit vectors in the x and z directions, or x-hat and z-hat)

(previous problem: A square loop of wire on the x-y plane with four corners of (0,0,0), (1,0,0), (1,1,0) and (0,1,0) carries a current of 10 A counter clockwise.)
