Starting Outside the Region with the Magnetic Field,a Single Square $\vec { B }$

question 44

Multiple Choice

Starting outside the region with the magnetic field,a single square coil of wire enters,moves across,and then leaves the region with a uniform magnetic field $\vec { B }$ perpendicular to the page so that the graph shown below represents the induced emf.The loop moves at constant velocity $\overrightarrow { \mathbf { v } }$ .As seen from above,a counterclockwise emf is regarded as positive.In which direction did the loop move over the plane of the page?

• A)The loop moved from bottom to top.
• B)The loop moved from top to bottom.
• C)The loop moved from left to right.
• D)The loop moved from right to left.
• E)All of these directions of motion will produce the graph of emf vs t.
