A 045-M Metal Rod Moves 0

Multiple Choice

A 0.45-m metal rod moves 0.11 m in a direction that is perpendicular to a 0.80-T magnetic field in an elapsed time of 0.036 s. Assuming that the acceleration of the rod is zero m/s², determine the emf that exists between the ends of the rod.

A) 1.1 V
B) 0.27 V
C) 0.076 V
D) 9.1 × 10^-5 V
E) This cannot be determined without knowing the orientation of the rod relative to the magnetic field.
