A very long horizontal wire carrying a current I1 = 35.0 A to the left as shown is placed tangentially below a loop of radius r = 0.0200 m (the wires are insulated, so there is no danger of electrical contact). Find what current I2 must flow in the loop, and in what direction (CW or CCW), so that the net magnetic field at the center of the loop becomes zero. NOTE: Answers must include units. The current I2 in the loop is . The direction of current I2 in the loop is .
