A) nearest the top and the bottom of the page.
B) nearest the left and right sides of the page.
C) parallel to the face and the backside of the page.
D) None of the above is correct.

Question

Quizplus · Accepted Answer

The emf is developed between the two surfaces nearest the top and the bottom of the page because the magnetic field is pointing out of the page and the cube is moving toward the right side of the page. This causes the electrons in the cube to move toward the left side of the page, creating a positive charge on the right side of the cube and a negative charge on the left side of the cube. The emf is the potential difference between the two sides of the cube.
