(a) Use a right-hand force rule to find the direction of the current in the wires shown in Fig. 19.36. In each case, the magnetic force direction is shown.

(b) If in each case the wire is a straight segment 15 cm long carrying a current of 5.5 A, and is in a B-field whose strength is 1.0mT, determine the magnitude of the magnetic force.
