Re: [AV Media Matters] Magnetic fields

While I can't offer you an answer to your question, I would suggest that you
not limit your question to just radar on a ship.

A friend of mine used to run the "television station" on a US Navy ship, and
he would tell stories about what would happen to his monitors when they
would turn on the big degaussing coil that was built into the ship.
