Hello, I know this sounds a bit like a silly question... but then again, I am curious if there is any truth to it. I have googled around a bit, and most search results are about electromagnetic fields of cell phones, cell phone towers, WiFi routers etc. But what about amplifiers? One with a big fat transformer it it? My common sense tells me, as long as the amp is off, there shouldn't be any magnetic field, so nothing to worry about. But maybe I am wrong?
