A 0.200-m wire is moved parallel to a 0.500-T magnetic field at a speed of 1.50 m/s.What emf is induced across the ends of the wire?
A)2.25 V
B)1.00 V
C)0.600 V
D)zero

The emf induced in a wire moving parallel to the magnetic field is zero because the magnetic flux through the wire does not change. The formula for induced emf involves the rate of change of magnetic flux, which is zero in this scenario since the motion is parallel to the field lines.
