Dont let little kids play with a magnet near your TV or old monitor. LOL.
I built this degaussing coil 5.5" diameter, 1/4" thick, wound on the lathe, #24 enamel coated copper wire, about 1000 turns, glued together with polyurethane varnish just like they do in transformers.
I used a light bulb as a resistor. The light bulb, coil, electrical cord are all in series. Not knowing what to expect I used a tiny 25 watt light bulb first and plugged the cord into the wall. The degaussing coil worked very well but did not completely fix the TV. Next I tried a 100 watt light bulb, WOW what a difference in the magnetic field. I had to move back 21 feet to be far enough away so the magnet field did not effect the TV. That freaks me out that means there is a 20 foot diameter circle magnet field around that coil. Next I tried a 60 and 40 watt bulb and finally got the TV and the old computer monitor degaussed.
