Part A: Which of the following changes would induce an electromotive force (emf) in the loop? When you consider each option, assume that no other changes occur. WHich of the following are correct, and there can be more than one answer.
A) The magnitude of increases.
B) The magnitude of decreases.
C) The loop rotates about the vertical axis (vertical dotted line) shown in the diagram.
D) The loop rotates about the horizontal axis (horizontal dotted line) shown in the diagram.
E) The loop moves to the right while remaining in the plane of the page. F) The loop moves toward you, out of the page, while remaining parallel to itself.
Part B: Find the flux through the loop. Express answer in terms of x, y, and B. Part C:If the magnetic field steadily decreases from B to zero during a time interval T, what is the magnitude E of the induced emf? Express answers in terms of x, y, B, and T.
