A coil gun would use repeated magnets that turn on and off, similar to a Monorail train.
Another cool one is a Rail gun, using electricity (alot of it) to propel objects.

nope... that type of launch system would use coils as electromagnets which are switched electronically to attract then repell the magnets... have a google for 'coil gun' & check out the wikipedia answer

what about for launching a coaster with magnets?
does that use eddy currents?
p.s. sorry im asking all these questions. im only 14 and im trying to learn about this kind of stuff

yep... as heat

i guess into the object its moving on
guitarshop29 2 years ago
yep, you got it...
no extra electrical input, just the force of gravity vs magnets makes the alu section fall alot slower than you'd expect. (The same principle is used on some rollercoaster rides for braking.)
Q for you...
something falling/moving has energy... where does that energy go when the object falling/moving is being slowed?

so there is no extra source of electricity?
just the eddies?
guitarshop29 2 years ago
the eddy currents are electricity... the magnets induce electron flow within the aluminium and as there is nowhere for the elctrons to flow to, the electron movement is turned into mangetism... type "eddy currents" into google & look at the wikipedia page for a more precise answer :)
