Question

identifying tools to test for magnetic fields
which would you sprinkle around the electromagnet that you produced in the laboratory activity to see its magnet field lines? iron shavings
which would you use to determine the direction of the field lines around a magnet?
which would you use with a circuit to determine if a magnet was moving in close proximity to the circuit?

Explanation:

• A compass is used to determine the direction of magnetic field lines. The needle of a compass aligns with the magnetic field.
• A galvanometer is used with a circuit to detect if a magnet is moving near the circuit. A moving magnet near a circuit can induce an electric current, which a galvanometer can measure.

Answer:

• For determining the direction of the field lines around a magnet: compass
• For using with a circuit to determine if a magnet was moving in close proximity to the circuit: galvanometer
