Lab: Electromagnetic Induction

Question 104870 • TX-Physics B

Which actions are ways to manipulate the magnet and wire loop in order to induce a current? Check all that apply.Move the magnet forward.Move the loop away from the magnet.Place the loop right next to the magnet, both stationary.Move the loop sideways.Move the magnet and loop in the same direction, at the same speed, at the same time.Rotate the loop in place.

Answer
A
Move the magnet forward.
B
Move the loop away from the magnet.
C
Place the loop right next to the magnet, both stationary.
D
Move the loop sideways.
E
Move the magnet and loop in the same direction, at the same speed, at the same time.
F
Rotate the loop in place.

Explanation

A current is induced when the magnetic flux through the loop changes. Moving the magnet forward, moving the loop away, or moving the loop sideways changes its position relative to the magnet’s magnetic field; rotating the loop changes its orientation to that field. Keeping both stationary causes no change, and moving them together at the same speed in the same direction keeps their relative position unchanged.
