Question

A laboratory magnet (see the figure) with a field B = 0.20 T over an effective area 18.0 cm in diameter exerts a force on a current-carrying wire that crosses between the pole faces at right angles to the field. The current in the wire is 12.0 A. What is the magnitude of the force on the wire?

B. What is the direction of the force? (left, right, up, down, front, back)
