Gauss Gun/Lenz's Law

This Gauss gun is an experiment involving electromagnetic fields. It includes a 15 inch wooden beam, a strong magnet, and five steel balls. It also includes reference material and an additional experiment.

This set consists of the following:

1) A 15 inch aluminum channel
2) Five steel balls
3) Seven circular magnets (stacked together-DO NOT SEPARATE)
4) One cubic magnet (EXTREMELY STRONG!)
5) One steel (nonmagnetic) cylinder
6) Two wooden channels

Experiment #1

Demonstrating LINEAR ACCELERATION

Select the WOODEN channel with the cubic magnet. Configure four steel balls on one side of the magnet and then slowly introduce the fifth ball on the short side by allowing it to roll into the magnet.

MAKE CERTAIN THAT THE CHANNEL IS POINTED IN A SAFE DIRECTION! After firing the first ball you may choose to fire the remaining ones and observe what happens. The internet is a good source for an explanation. Note you may want to compare this experiment to “Newton’s cradle”!

Experiment #2

The second experiment involves Lenz's Law.

Lenz's Law states:
An induced electromagnetic force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current.

Hold WOODEN channel with index fingers blocking the ends. Cause the cylinder to roll in the channel by tilting the channel left to right. This can be done at varying speeds and to varying degrees. Replace the cylinder with the stacked circular magnets. Now repeat this procedure using the ALUMINUM channel. The difference is Lenz’s Law in practice.

MAGNETS CAN BE DANGEROUS! Do not allow young children to handle them. DO NOT SWALLOW! Be careful to avoid being pinched, magnets are very strong.
