EM stands for electromagnetic and propulsion means something that pushes, thrusts, or drives an object forward, for instance - releasing a pulled rubber band on a sling shot propels an object resting on the bands surface. Therefore, EM Propulsion literally means electromagnetic thruster. What's so special about this? I use this principle to get my spaceship off the ground and into space! Imagine in the picture to the right that my spaceship is the green ball and the blue sling (like the rubber band of a sling shot) is a moveable metal platform connected to two stationary rails. The moveable platform holds my ship. A large current flows from the surface of my planet where a source exists through one rail then the platform and finally back to the surface by the remaining rail. The current interacts with the magnetic field at the platform thereby lifting and accelerating the platform with the ship into the sky. There must be a considerable amount of current needed to get my spaceship out of the planet's atmosphere. This is where the calculations come in. Assume that the magnetic field and the gravitational pull of Xenon is a constant over the length of the rails.

*L is the length of the rails in meters

Wow! A current greater than gm/BoW must be supplied to lift the ship from the planet’s surface. To propel the ship into space, a current greater than (m/B_ow)[g+(v_x1²/2L)] must be supplied. More current is probably needed because of friction.
