Which of the following statements about the motion of the conductor in the magnetic field region are true?
a. The conductor slows down when it enters the B field region and it speeds up when it exits the region.
b. The conductor slows down when it enters the B field region and it slows down again when it exits the B field region.
c. The conductor slows down when it enters the B field region, consistent with conservation of energy.
d. The conductor produces a magnetic field in the k direction when it enters the B field region, and it induces a magnetic field in the +k direction when it exits the B field region.
e. The conductor produces a magnetic field in the k direction when it enters and exits the B field region.
f. The conductor produces a magnetic field in the +k direction when it enters and exits the B field region.
