Starting Outside the Region with the Magnetic Field, a Single

question 3

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 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.
