(a) A 0.730 m long section of cable carrying current to a car starter motor makes an angle of 60.0° with the earth's 5.50 10-5 T field. What is the current when the wire experiences a force of 7.00 X 10-3 N?

(b) If you run the wire between the poles of a strong horseshoe magnet, subjecting 5.00 cm of it to a 1.95 T field (perpendicular to the wire), what force is exerted on this segment of wire?
