Problem
A straight wire is suspended horizontally along the east–west line and carries a steady current of 5A from west to east. The region is under a uniform magnetic field of 0.2T that points vertically upward.
(a) In which cardinal direction will the wire tend to move?
(b) If the current is reversed while the field remains unchanged, what will be the new direction of motion?
