How do you test for a permanent magnet?

Answer 1

One way to test for a permanent magnet is to use another magnet. If the object is attracted to the magnet, then it is likely to be a magnet itself.

Another way to test for a permanent magnet is to use a compass. Place the compass near the object and observe if the needle moves. If the needle is attracted to the object and aligns north-south, then it is likely to be a permanent magnet.

Additionally, you can test for a permanent magnet using a gaussmeter which measures magnetic fields. If the gaussmeter detects a magnetic field near the object, then it is likely to be a magnet.
