(attachment photo showing the fully set up demonstration)

Description:

The thermoelectric magnet consists of a copper loop wrapped around the iron core.

Setup: Note: Make sure that one of the red & white gas cart are in placed and the gas hose is connected to the utility trench gas line. The gas cylinder that supplies the gas to utility trench gas line may or may not be connected/installed and should be inspected.

1. Clamp the 1/2' rod with the table and the another one to make a hanger bar.
2. Make sure that you clamp copper loop in magnet body and suspend magnet.

Cautions, Warnings, or Safety Concerns:

1. Beware of heat flame.
2. Demonstration may require practice.

Demonstration:

Clamp copper loop in magnet body and suspend magnet. Show the students that there is no magnetic power from the thermoelectric magnet by apply armature concentric with magnet body and it cannot attach to the magnet, then heat one junction with burner and cool the other with cold water. Apply armature concentric with magnet body again. Attach hanger and add weights as heating progresses. To function properly, magnet and armature must make perfect contact.
