A small loop of copper wire is inside and held perpindicular to a large, uniform magnetic field. You move the loop in circles and vary the speed. What do you observe?
a. The faster the speed, the greater the current. |
|
b. As you decrease the radius of the path of the loop in the field the current increases. |
|
c. As you increase speed, the current decreases. |
|
d. Nothing. No current is induced. |
