[QUOTE="Silas Pradetto, post: 16302, member: 34"] Re: Electromagnets I know the effect of AC and DC on the electromagnet, but what is the effect of varying the frequency of the AC? I'm sure you won't be able to notice the varying field picking up paperclips with a magnet made from a bolt and some wire. I'm going to have to try it, using an old amplifier as a voltage/current source. [/QUOTE]
