Help Please! Rube Goldberg Project Rutt
Hi Everyone I have a problem!
I am trying to find a way to make a Rube Goldberg project where I have fake lego man with magnets on his hands and feet with acrobat bars that "swing" back and forth and the man is suppose to clip to the next bar of increasing strength of the magnetism till he gets to the end of platform on the other side. I problem right now is I am trying to find a set of magnets in increasing/decreasing strength to finish the project but I have no idea where to find them.
If any one has any ideas I could really use some right now! I have concept drawings! You would have my undying gratitude.
Thank you!

if you wrap a magnet in 5 layers of tape, strength will be diminished . If you wrap it in 20 layers, it will be weaker still .

how about electromagnets?

Better way would probably be to mount the magnets on the swinging arm on some kind of adjustable slide device. That way, you can vary the distance to the contact point and get the exact needed power of the magnet to attract the free object. It might be tough to get stepped power magnets exactly in the strength you need. There is some formula to calculate magnetic strength over distance... Good luck.

But I guess my ultimate question is how do you slide it while in motion I guess.

The magnets are locked into position at the end of each trapeze. You just need to embed steel nuts or screws in Lego man's feet and hands. Have a piece that has a slot over a bolt/wingnut to make the extending trapeze or duct tape the magnets in place at the right length when you get it working.
