A bar magnet moving toward the left end of a stationary solenoid.
A bar magnet moving toward the left end of a stationary solenoid.
A bar magnet is oriented horizontally with its south pole facing the left end of a stationary, closed-circuit solenoid. In Trial 1, the bar magnet is moved to the right toward the solenoid at a constant speed v. In Trial 2, the bar magnet is moved to the left away from the solenoid at the same constant speed v. Which of the following correctly identifies the magnetic pole induced at the left end of the solenoid and the direction of the magnetic force exerted by the solenoid on the bar magnet for each trial?
