The item in photo is a coil of 20-gauge copper wire (with enamel or varnish insulation), is 12 inches in diameter, weighs close to 5 pounds and has a resistance of about 25 ohms. The coil is wrapped with electrical tape. Appears to have been homemade. Found it in a box of electrical odds & ends which I rescued, to keep some potentially good (?) stuff from going to the landfill.
