My Neodymium Magnet Powered Catapult

http://MagnetNerd.com Opposite poles attract, like poles repel, and if you have really big magnets they repel a lot. I decided to take advantage of this by constructing a Catapult powered by the repelling force of a pair of 2" dia by 1" thick Neodymium Magnets with a pull force of 230 lbs. I built it from red oak with brass hardware near the magnets and steel nuts and bolts at the pivot. The ammunition is beanbags.

You could post more videos with these magnets in repulsion, I found your videos very cool, sta congratulations!

Hello, I wonder, how many pounds can withstand these magnets in repulsion?

And how did you do to unite the two sides, the magnets are very strong!

hahahaha that is brilliant A+++++

[flyingmen2]

nice concept

[TheDudeFromCI]

How far does it shoot?

[jasanpahaf]

haha, nice toy

[ryan50ryan]

that's pretty sweet.

And yes these can be man made there are 2 methods: There are two principal neodymium magnet manufacturing routes: 1. The classical powder metallurgy or sintered magnet process 2. The rapid solidification or bonded magnet process

Neodymium magnets are Nd2Fe14B a rare earth magnet made of an alloy consisting neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure

jk they an alloy with a high density and saturation limit for magnetism the alloy is neodymium, iron, and boron soooo yeaa........
