Thermocouple magnet: Flame with water cooling holds weight.

Thermocouple magnet: Flame with water cooling holds weight. A thermocouple is formed when two dissimilar metals are joined at two endpoints. A small voltage is produced when the two endpoints are at different temperatures. This thermocouple magnet has just two coils of thick copper (resistance about a millionth of an ohm) and another piece of copper-nickel alloy (placed between the coils). When one end is heated with a bunsen burner, and the other end is cooled with cold flowing water, a voltage is generated on the order of millivolts. The current thus generated in the copper coils is on the order of a hundred amps. The current generates a large magnetic field which is reinforced by the 2 iron cores inserted inside the 2 copper coils. Under optimal conditions, this thermoelectric magnet is able to support over 200 pounds.
