PURPOSE: To show that a small amount of energy can produce large magnetic forces.

DESCRIPTION: A magnet and keeper are held together by energizing the magnet with a flashlight battery. It usually takes more than one person pulling on each side to separate the magnet and keeper.

SUGGESTIONS: After two of the strongest guys in the class can't separate the magnet, separate it yourself (after discreetly turning off the battery by flipping the switch), suggesting that they are really wimps.

REFERENCES: (PIRA unknown.)

EQUIPMENT: Battery operated magnet with keeper.

SETUP TIME: None.
