Do Electromagnets work Underwater?

Click For Summary
SUMMARY

Electromagnetics, as described by Maxwell's Equations, function effectively underwater, confirming their operational capacity in aquatic environments. However, electromagnetic wave propagation, particularly for radio and light waves, experiences significant attenuation in water. While blue light can travel reasonably well, typical radio transmissions are severely limited. The Navy has successfully utilized very low frequency radio waves for underwater communication, demonstrating specific applications of electromagnetism in marine contexts.

PREREQUISITES
  • Understanding of Maxwell's Equations
  • Knowledge of electromagnetic wave propagation
  • Familiarity with light spectrum behavior in water
  • Awareness of magnetohydrodynamic drive principles
NEXT STEPS
  • Research the applications of very low frequency (VLF) radio waves in underwater communication
  • Explore the principles of magnetohydrodynamic drives and their uses
  • Study the attenuation characteristics of different wavelengths in aquatic environments
  • Investigate the behavior of blue light and its implications for underwater visibility
USEFUL FOR

Marine engineers, physicists, and anyone interested in the applications of electromagnetism in underwater environments will benefit from this discussion.

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.
