Hi all,
Everyone is familiar with what a older 10 inch degausing coil loop looks like.
It works with 120 volts AC at 60 HZ and is used to degauss tv monitors.
I am trying to find a way to power that same type/size of coil loop whereas I can control the frequency from 0 on up to say 300 HZ.
Does any one have a simple 10 inch loop variable frequency oscillator circuit ( single transistor) thats fed with a low dc voltage power supply. Say 12 to 19 volts DC.
This loop then should be able to transmit this lower frequency a short distance. Frequency could be selected to whatever desired.
Any help will be appreciated.
Thanks, Tom
