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?
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?

Answer 1

To visualize the magnetic field lines around an electromagnet, sprinkle iron filings around it. Use a compass to determine the direction of field lines around a magnet. A Hall effect sensor can determine if a magnet is moving near a circuit.

Step-by-step explanation:

Identifying Tools to Test for Magnetic Fields

1. To see the magnetic field lines around an electromagnet, you can sprinkle iron filings around it. The filings will align along the field lines, giving a visual representation of the field.
2. To determine the direction of magnetic field lines around a magnet, you can use a compass. The needle of the compass will align with the field lines, pointing towards the north pole of the magnet.
3. To determine if a magnet is moving in close proximity to a circuit, you can use a Hall effect sensor. This sensor detects changes in magnetic field strength and can indicate the presence of a moving magnet.

Using these tools, you can investigate and understand the properties of magnetic fields and their interactions with magnets and circuits.
