Currently I've become more intrigued with Magnetic shielding.
Magnetic repulsion wheels usually don't work because the force
required to push the North(or South)-poles of stator magnets &
rotor magnets near eachother is equal to the force with which
they repell eachother.
Magnetic shielding can cancel out the repelling force that
resists the stator- & rotor-magnets being brough closer to
eachother, so that the repelling force pushing them away
from eachother is allways greater.
This video explains it well:
This is what I want to build a protoype of now.
MU-Metal is a material that has Magnetic Shielding properties as is
clearly demonstrated in this video:
Just hope I can aquire a bunch of MU-metal plates(from Harddrives) without
spending too much money. I might need 8 or 16 of them. I just don't know
where I can buy MU-metal. Anyone? Maybe I'll look around for old, broken
hardrives to harvest the MU-metal plates.
If anyone has access to MU-metal or lots of old harddrives & some time to
spare, please do feel free to build this shileded, magnetic wheel.
As a side Note: MU-metal clearly blocks magnetic fields pretty effectively.
According to Wikipedia "Permalloy" is also a good shielder of magnetic
field lines, allthough all day I haven't been able to access the Perm-
alloy Wikipedia article. Can anyone try and see if it is accesable to them?
PS:
I'm having trouble accessing many websites today. Anyone else experience
this today? Earlier today I had problems connecting to youtube and since
about 10 minutes ago I cannot access both Google.com % Wikipedia.org.
And when I can access google I cannot access any of it's links.
Anyone else had/having trouble with this?
