Magnetic Gate - need help with school project
« on: January 06, 2016, 11:49:24 AM »
Hi everyone,

I have a little magnets project for school i need to accomplish and I'm a little stuck.. hoping someone with the right knowledge of magnets could assist me here :)

I need to build a small magnetic gate which can push forward a steel ball (but not too far away). the idea is to roll the ball on a desk and when it enters the gate it will shot it out forward. I'm trying to do that either with hallbach array or other setup of neodymium magnets.

So I've built the Halbach array but couldn't get the correct setup to make it ball push forward with force.
- should i try a different set up? maybe a tri gate will be better for this experiment? or maybe I'm trying to do something which is impossible.. ?

any help will be great!
thanks in advance, tom.

Click ""TRI GATE"" on You Tube and you will see lots about that sort of setup.

Hope this helps.

Try "Calloway V gate"
.

Here is a link to a "clanzer" video.

http://www.youtube.com/watch?v=VD1WgwZ9-Oo

If you can change your runner from being a single steel ball
to the stacked magnet and dual ball runner you will be
ahead I think.

Clanzer also had a video where he mounted the magnet
runner on a red plastic firetruck. So the runner had only
linear momentum to contend with, and not rotational momentum.
The video was quite convincing that this seems *could* be set up
to go on "forever"  The halbach arrays eliminating the tendency
of the field magnets to form a powerful "sticky" spot.
In fact you could use track field geometry to augment the
movement of the runner in certain cases of a low friction carriage.
