Problem
A straight horizontal conductor AB lies along the east–west line. It is quickly pulled vertically downward through a uniform magnetic field that points from north to south. What is the direction of the induced current in the conductor?
(a) West to East (B → A)
(b) No current is induced
(c) East to West (A → B)
(d) North to South along the conductor
