Magnetic Brakes

[honeybunchickens]

Why don't they put this design on cars yet? Its a brilliant concept and you will never have to change brake pads

[tanmaykothari1]

it was ok



[sondeleb]

Very nice demonstration

[4141ca]

this is used in f1 for braking and charging the kerbs

[MarineFocus]

cars brakes don't even work that way -.- wth is he saying

the brakes itself stops the tires from turning which creates friction with the ground and thats how the car slows down...

I don't see how you can apply that to cars? unless you meant replacing the rubber braking parts with the magnetic brakes... okay, more efficient in not wasting rubber but thats not going to help cars slow down faster unless the GROUND magically supports magnetic brakes.. which is like wtf

other than that cool vid

@MarineFocus Most cars use brakes, which are just metal slabs with lots of friction, that rub against the inside of the wheel, causing friction, causing the wheel to stop. It has nothing to do with the ground. When magnets interfere with copper or aluminum it has a slowing reaction which could be applied to cars to slow them down.

[MarineFocus]

@xXCrimsonVirtueXx What you're saying is true, but what I meant was since the slabs that "rub against the inside of the wheel" is working efficiently enough already, there's little reason to use magnetic brakes (I'd imagine it'd also be high maintenance to keep it up to par?). And continuing from above, when I mentioned the ground I meant the car stops BECAUSE of the non-moving tires (assuming the wheels lock from the brakes) that rubs against the ground.

im really intrested in how that is possible, how come the magnet doesnt attach to the pendulum? or does it have to be magnetised?

[tomT024]

some roller-coasters use this...

Ok, but you have to admit that if you compare the magnetique fiel brake to a conventionnel brake systeme there's a huge difference in the temperature.

For an example take an electric motor: the most of the heat is produce by the bearing, wich is friction. I bet with a magnetic brake you can put your hand on the systeme after braking for a mile long hill, but on a conventionnel disc brake and pad systeme you would end up at the hospital with severe burn lol.

O M G !

[muzammilali007]

some super cars have already been using magnetic braking mechanism for years now, the car that broke the ground speed record also used it.

Great video! It reminds me of dropping strong tiny rare earth magnets through a copper tube and watching em fall....they will fall as if they are in slow motion, as if in moon gravity, for the same reasons as here. I am wondering is it possible to store the energy from the current created into a battery at the same time, or would that somehow dampen the braking effect?

[freebiker75]

What i like about it its the fact that there is no friction, no wearing parts and no heat produce.

[SZDarkhack]

@freebiker75 It's not true that there is no heat produced, the kinetic energy has to go somewhere, doesn't it? It dissipates as heat produced by the current induced in the metallic pendulum (or brake disc in the case of an automobile breaking system).

[freebiker75]

its not what truck sometime use on the the drive line to help to stop???

[tropicalease]

I get the idea though would the magnets stop a pendulum weighing say twice as much...???....What's the ratio of weight to power etc...???

[Dorothyinstead]

Excellent demonstration!

[gioraver]

where i can found more information ?

[b7ish]

What kind of magnets did you use.

[rodneyxiong]

cool
