Question
Ms. Rivera is demonstrating an experiment that includes the use of a compass. A compass has a small magnet that rotates to align with Earth's magnetic field. This small magnet of the compass is called a needle. The model below shows the experiment that Ms. Rivera is demonstrating.
What will most likely happen to the compass needle when the switch is closed and the circuit parts are connected to the battery?
A.
It will point toward the batteries because they are the only circuit part that can be magnetic.
B.
It will turn around once because the completed circuit reverses Earth's magnetic field.
C.
It will remain stationary because there are no magnetic materials included in the circuit.
D.
It will move because the current in the completed circuit will induce a magnetic field.

The correct answer is: **D. It will move because the current in the completed circuit will induce a magnetic field.**
When the circuit is completed by closing the switch, a current will flow through the circuit. This current generates a magnetic field around the wire, which can interact with the compass needle, causing it to move. The compass needle, which is a small magnet, will align itself with the induced magnetic field created by the current.
