Re: Generating EM field
If the frequency is low and one would want a nice sine wave, simply using a transformer with two windings would allow a nice and simple feedback generator. Open the core by taking out some laminations and you have a nice field generated. This is a technique used for bulk erasers for tape and other magnetic media.
