Magnetic Accelerator

Newton would have loved this discrepant event!

A great introduction to the concept of magnetic potential energy. Using a double-sided ramp and a series of steel marbles, you initially demonstrate Newton's First Law by rolling one steel marble down the ramp to collide with a resting group of marbles. Not so impressive so far...

While setting up to repeat the demo, replace the first resting steel marble with a magnetic sphere. Your students will be amazed as the collision shoots the last steel marble right off the ramp!
