what the a b c

A one loop square coil, 3.50 cm per side, carries a current in a clockwise direction of the 200 mA. The loop is inside a solenoid, with its plane perpendicular to the magnetic field created by the solenoid. The solenoid has 460 turns per meter and carries a current of 15.0 A. a) How much is the magnetic field created by the solenoid? b) How much is the magnetic force exerted in each side of the square loop? c) How much is the net torque exerted on the square loop? d) If the square coil is moved 250 from its original position, how much will be the new torque on the coil? 15.0 A 10.200 A X
