Do magnets work underwater?

Question

OK so I was thinking about science fair project ideas, and I thought of a project with the question "Do magnets work better in fresh water or salt water?" Of course, first I have to find out if magnets work underwater. Does anybody know if they do? Thanks in advance!

Answer 1

YES, THEY WORK

Answer 2

Yes they do, mostly because water itself is non-magnetic and doesn't impact to that appreciable degree the field lines of the magnet.



A compass is just a magnet on a pivot, so provided that there's no mechanical breakdown (like getting crushed by the water pressure or flooded to the point that the frictional force of the water is greater than the force that would cause the magnet to orientate north) it should work underwater, too.

Answer 3

Of course they do,



The magnetic field will be differnet due to the different "mu" of the water, but sure, they will work.

Answer 4

Yes!

Answer 5

Yes they just create a field they work equally in pretty much any environment

Answer 6

yes

Answer 7

NO.... oh i mean yes
