Dynamic Geomag: Friction-Free Transmission Gear

The magnetic teeth make the two wheels work as a 10:5 friction-free trasmission gear.

I denti magnetici fanno in modo che le due ruote si comportino come un riduttore 10:5

[yomomasface]

is that caused from the magnetic pulls?

[aldoaldoz]

yes

[SIP100]

air resistance... not friction free.

[aldoaldoz]

Sorry, I'm alone here: I operate in a vacuum!!! :)

How long does this action last once started?

[findthecomputerroom6]

@64298 if there is zero friction then technically in should go forever

[MrLuke370]

@aldoaldoz most be space you are working in or else you are the richest man in the really god vacuum business cos there are still particles there for friction to occur... really cool tho.

[Pyanapple]

This is awesome and I'm 14 and have no idea how I got up here, but look at that!!

[PrimeTargetSecurity]

thx for giving me a new idea. i dont use these toys tho, i gotta nice source on strontium magnets. strong lil'fukrz. i own a custom shop & a security firm so i have these subs i sell and they use 120oz, 140oz, and 240oz magnets made of strontium with the coil being made of kapca (a patented metal) so by mixing 2 worlds i've got alot of ideas working out and this gives me a great idea 2 try. thank you. for the serious ones reading this, try speaker techology and ground-interupt tech. works.

@SIP100 So true there is also friction on the contact of the ball magnets! :p

[pyroblaine]

if you give a 10 year old a Phd in physics this is what he will come up with for a thesis..... either that or a really cool robot ^.^

[ross9886]

I believe it will lose energy as heat, caused by eddy currents in the metal parts, which are induced by the moving magnets. As for friction, you should try to levitate the two gears, that would be so cool. Imagine a contact-free drivetrain... Damn, I gotta get some of these geomags!

@aldoaldoz Still not friction free in a vacuum...

[Soulrider2012]

This is not friction free as common sense as well as the laws of physics dictate there will be friction. It will not spin perpetually either. It will spin for a short while and stop unless someone introduces more energy into the system (spins it by hand, like he did to start it before filming).

@aldoaldoz how is it possyble to work in a vacuum?, and dont the balls theirself provide frictrion?
