Bleh, I wanted to draw out pictures but I'm too lazy. Besides, videos are better sources of teaching material.
Here's the basic idea.
^Take this experiment using a Gaussian Acceleration device. A steel ball rows along a rail, striking a row of stationary balls. As you can see, the last ball is pushed away at the same speed as the striking ball. The law of energy and momentum conservation. But now, let's add to the rail a powerful neodymium magnet. Watch. Prior to impact, the rolled ball receives instant acceleration from the magnet. That speed gets transferred to the ball at the end. (P.S remember to rate and subscribe)
