Introduction
The magnetic accelerator demonstrates the concept of magnetic potential energy. It also depicts Newton’s first law by rolling a steel ball down the ramp making it hit the resting group of marbles in the ramp. The experiment propels steel balls at high speeds through the concept of magnetism.
For Magnetic Accelerator (with firing trough)
-2 small Magnet Balls( Rare Earth Magnets)
-8 small steel balls
-Steel ball bearings
-A 25cm (10") long firing trough
Materials
Procedures
For Firing Trough:
Place two small balls on a linear rail and arrange the balls. Then, carefully place the small magnet at the end of the rail, this will cause the magnet to transfer energy to the other ball. The last one will shoot off the rail at a high speed.
For Ramp:
Place the eight balls on the track and then add a magnet ball at last. Release one more magnet and let the magnet touch the balls. When it touches the balls the Principle of Momentum and conservation of energy begin to apply and the last ball will shoot of the ramp.
Lab Safety:
Becareful when handling magnets due to the fact that they are exreamly powerful. When removing magnets appart from eachother, be very careful. If the magnets manage to escape your grip and they connect with eachother it can pinch your skin if it gets in the way, this is really painful, so watch out!
For Magnetic Accelerator with Ramp:
-Magnetic Accelerator Ramp or Track
-8 Large Steel Balls
-2 Powerful Rare earth Magnets

Principles and concepts
The magnetic accelerator demonstrates the concept of magnetic potential energy. When the ball at the top of the ramp is released, kinetic energy takes place. It also depicts Newton’s first law by rolling a steel ball down the ramp making it hit the resting group of marbles in the ramp. The experiment propels steel balls at high speeds through the concept of magnetism. When the last ball shoots off of the ramp the principle of momentum and conservation of energy is depicted.
