Starting Outside the Region with the Magnetic Field, a Single

question 12

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 perpendicular to the page so that the graph shown below represents the induced emf.The loop moves at constant velocity .As seen from above, a counter clockwise 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.
