How can a compass be used to check the strength of an electromagnet?

Answer 1

see if a magnet will stick to it

someone who knows stuff about magnets please improve this answer. I myself do not know because a magnet will not stick to a very weak magnet but it is still magnetic.

EDIT

why would you answer if you don't know the answer?

You stroke a bar magnet on the material and after a while it either becomes magnetic or not. unless its already magnetic which you would know straight away because it would stick to the bar magnet.

sorry if any of my answer doesnt make much sense ... hope i helped someone

Answer 2

The most basic experiment involves these materials:

- several paper clips

- your electromagnet

If you want to test the strength of the electromagnet, put some paper clips at a nearby distance and see how many are attracted to the magnet. If you want to compare it with other electromagnets with different strengths, just record the numbers on a table.

Answer 3

repulsion is the sure test of magnetism. Narahari.D

Answer 4

if the electromagnet is strong the compass will point to it not north but if it is weak it will still point north

Answer 5

The best way would be to use a magnet itself. You can decide on the object's magnetism based on whether or not there is attraction or repulsion between the object in question and the magnet.

Answer 6

which electromagnet design was most successful in picking up the most paper. clips

Answer 7

look how much it can hold

Answer 8

repulsion
