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.
