Do Electromagnets work Underwater?

    Hello;

    Just a question that I have been thinking about. Is there some reason why they wouldn't work in water?

    Thanks.

    You need to clarify the question a little more.

    Electromagnetics in the sense of (Maxwell's Equations) do work underwater. However, electromagnetic waves (whether radio or light) do not propagate particularly well underwater, if that is what you are asking.

    Blue light propagates reasonably well under water, so there is an example of wave propagation. Also, I believe the Navy has used very low frequency radio waves underwater. However, typical radio transmissions are highly attenuated under water.
