# Thread: Giant Magnetic Launching Device

1. Would it be possible to somehow use the forces of magnetism to harness the pull and specifically push effect to launch spacefaring devices? Think of a tube with one end blocked, so the cylinder (spacecraft) inside, can only escape one way. Building the magnetic fields to such proportions the tubes top is slightly opened to allow the cylinder to escape at some velocity.

Could enough force be put on the craft to get it out of orbit? This is similar to pressure building up and then the top exploding out, except the pressure is already built and what sets of the propulsion is the slight adjustment of the lid to allow the cylinder to escape?

2.

3. It's technically possible, to have an open tube and move the magnetic field up it so the craft follows. It isn't feasible, though, to use this technique for manned craft: "splat" comes to mind.

Yeah. However it would be an extraordinarily gentle means of accelerating fragile ferrous objects. Theoretically, you could punch a capsule full of poised mousetraps into orbit, without springing any.

In the same way, gravity accelerates the human body gently...

5. The 'fragile ferrous objects' will still withstand greater acceleration than the human body, though. The article I saw about this idea suggested that the satelite being sent into orbit would need to be accelerated over a mile or more, to reach the necessary speed. By contrast, a manned craft would need to be accelerated over several times the distance. So there

6. , just allow the manned portion to accelerate from the front of the craft to the back of the craft and you're fine, Jeese!

7. Isn't that like jumping up just before your plummeting elevator hits bottom?

8. NO! you accelerate downward to the half way point, at which point the acceleration of the craft ceases, and your pod will then accelerate up to speed with the rest of the craft at the same magnitude acceleration and you come to "rest" at the bottom. A 'slight' decrease in the force, but a decrease nonetheless and I refuse, REFUSE! to believe it's like jumping up in an elevator! GAH!!!
