Magnetic Cannon

Description:  The magnetic cannon contains four spaced neodymium magnets in a channel.  Two balls bearings are placed between each ball bearing.  When a new ball bearing is introduced a transfer of energy occurs and the final ball bearing leaves with a higher initial velocity than the first.  This is a great phenomenon for studying transfer of momentum and the energy of an object based on its position within a magnetic field.

Web Resource:  Magnetic Challenge with Bozeman Science

Magnetic Cannon Challenge. Paul Andersen from Bozeman science has challenged me when we met about the magnetic cannon, he wants me to figure out the physics behind a toy called the magnetic cannon. I'll post my answer to this challenge next week.
