  • Radical!

    

  • Guess the magnet motor did not work out !

  • 0:23 with a silicone rubber H-WH-EEL on it

  • Them's the brakes!

  • i Dont understand 80% of comments here @_@

  • I'd save so much money on brake pads :O

  • @nnecromancer123 Grammar Nazi here, the correct comment would be 'So many long comments O.O'

  • FYI, similar eddy current brakes are used on many modern roller coasters. We have vertical fins on the track that slot into permanent magnets on the train. The brakes are so powerful that we even use them to bring you to a safe landing on those massive drop tower rides. So the next time you're at an amusement park look for the vertical fins sticking out from the middle of the track and you'll know what they're for. :)

  • 0:0 HEYYY!!

  • The effect used here is called "Eddy current". During braking, the metal wheels are exposed to a magnetic field from an electromagnet, generating eddy currents in the wheels. The eddy currents meet resistance as charges flow through the metal, thus dissipating energy as heat, and this acts to slow the wheels down. The faster the wheels are spinning, the stronger the effect, meaning that as the train slows the braking force is reduced, producing a smooth stopping motion.

  • Telma brakes use already this principle based on the Foucault currents

  • Here's a logical question: Is it possible for that kind of braking system to hold something something still or something parked uphill?

  • @TheClawsofangels

    good question but no its not possible. the effects of the copper and aluminum only counter-act the magnetism in the wheel temporarely. if tou put that brake to use like that the car would roll down hill. the brakes only work if there is movement if that makes sense

  • hu-wheel! 

  • Damn it!

    I hate getting trolled by youtube videos!

  • This is a poor demonstration, seeing that when he applies the brakes he pushes it too far and creates friction to stop the spinning.

  • These are used in lifts and elevators... They are common just not so common in cars yet

  • That would fuck a cars shit up

  • train brakes work this way :) nothing new

  • i come to a quick stop because there's no weight pushing it forward, if there was a car it wouldn't stop as fast

  • similar systems are already in use around the world, when stopping trains and subways.

  • so much long comments O.O

  • You must be using a much more different dremel than mine - mine has 2 speeds - 15000 and 35000, and it heats up within seconds of turning on (you can't hold it with bare hands or it will burn you)

  • yeh it stops very quickly but it doesn't have a couple tyousand pounds of weight behind it either

  • They'll still get hot from the current, and magnets lose strength with heat, same as disc brakes, and it doesn't work well at low speeds. At a stop, they don't work at all. They're not viable for cars, but have been used in rail systems for years, in trains and rollercoasters. 50% cost savings over the life of a system.

  • ok its a good concept and im sure itll advance and get much better, but the practicality now is mediocre. it takes ~3 seconds to stop 2 small discs, but as a car brake or even a bike brake with weight on that.... you'd be better off trying to stop with your feet

  • That wheel isn't attached to the inertia of a 1/4 of a 7300lb Tahoe doing 75mph down a highway. It doesn't take much force to stop a light-weight spinning object. As a DJ or any kid who's plaid with a plastic fan.

  • @fakshen1973 but an amplified magnet, hmmmm...

  • @fakshen1973 youtube.com/watch?v=AgpV7zbvLx­g , I might not be an engineer but I know a guy whos wifes cousin is, so ...

  • @fakshen1973 you dont need to deliver rotational force to the wheels using a magnetic engine. You simply use it to create energy for the electric motors that turn the wheels

  • lolz u sez wheel funneh (no offences)

  • @aaronemem lolz u sez everything funneh (retard)

  • Comment removed

  • instead of inserting the copper plates into the spinning disc to start braking, would a switch connected between the two plates (which are positioned permanently to the side of the spinning disk) and ground have the same effect?

  • @AsKSniperMagician a 14000 lbs rocket car was slowed from 400mph in June 2008 using only magnet braking so looks like they work really well. I think because its contact-less, we'll see less issues with warped brake rotors, brake squeal etc. The real question is the size of the magnet field surrounding the magnetic braking system. I imagine though, it wouldn't be too difficult to shield an ECU from it.

  • ha but can it stop a bullet?

  • all i have to say is, bullet forcefield. fuck yea!

  • great idea, exept my only problem with this is that there is too much possibility of failure, what if the magnets go out of place or it gets hit with something, however traditional brakes cannot be used at fast speeds effectively, this is where this comes into perspective

  • this works, but its not really practical in a car unless you have a much more powerful magnet, which might interfere with the car's electronics. even though it does stop very fast, it doesn't factor in the kinetic energy produced by a car and its environment. i don't thing it would do much in a downhill situation XD

  • This concept has been used in most modern cardio gym equipment for resistance for over a decade.

  • Through the power magnetism...

  • HEEEEYYYYY!!!!

  • Hey slow down the car,*brakes* *crash* you stopped the car!!!

  • 0:23 What did he just say? " With a silicone rubber hwheel on it" !!!!! He put emphasis on the h. This is stewie when hes 40 years old

  • "oh hey that sounds interesting"

    *klicks on video*

    (random guy dude) "HEEEY! :3"

    *change video*

  • Penis Magnet. Girls are attracted to penis magnet.

  • they would have to be extremely powerful magnets to stop a whole car with people in it

  • if this is used as a brake system in a vehicle, will it be expensive?

  • ACCENT 

  • Now put some weight and power behind the wheels.there is nothing pushing the wheels to stop,noway is it going to be able to stop a car or anything important.If you think thats stopping very fast with no force or weight behind it,your mistakin,but also for it to be on a car/truck it would have to be energized to like a electric magnet to put the braking force needed,and also would be a problem if there is power loss to magnets.I'd stick with the pads before I'd trust magnets or any other means.

  • VSAUCE

  • so is just basically magnets and copper???

  • I love how people think that the braking system is an on/off system. The more surface area the magnet covers, the more braking force that is applied to the disc.

    Of course, a system like this would be pricey. Isn't everything when its first released? Think of all the safety features that came from the S class that are now part of pretty much every production car

    The ABS system could be redesigned to deal with lead foot braking instead allowing the car to slow down without flipping the car

  • the momemtum of a couple of spinning wheels vs that of a car, how would it be practical considering costs.

  • Sure, the vehicle comes to a stop, but will you? It's as if you're still slamming on the brakes, since inertia will guide you through.

    Unless I'm missing something...

  • It won't be long until we start using force fields. :D

  • ahh 240p We meet again 

  • I you would need to make a really fast brake and slam on your brakes would it stop the tires and prevent you hitting an object?

  • Get R Done

  • that's a good application !!

  • Vsauce sent me here

    

  • but what if the mass is bigger and the magnet has to stop a larger and heavier object? will it be just as effective?

  • i think that they use this technology in formula 1 racing, isn;t it?

  • This wouldt work in newer cars the magnatic field would ruin everything inside it.

  • such smart and valid arguments here... i should fuck that up

    BOOOOBS

  • I wonder if using supermagnets in your car is safe considering the electronics and computers that are used more often in modern vehicels.

  • redneck accent??? just askin?

  • "HEY"  :D

  • top comments are to long to read -_-

  • One, does the "pads" come into contact with the rotor in anyway, even if it's just the front part of the "pads" touching the hub of the rotor.

    Two, how would increased mass affect stopping time of these rotors.

  • HEY

  • hey

  • i saw his pants and the collar shirt he was wearing and i thought i was gona hear a " HI, BILLY MAYS HERE"

  • roller coaster

  • But did you see the Gorilla?

  • What is the annual cost to maintain a system like this on a regular sedan?

  • Cameraman: oopsie dasie i left the lens cover on derp can you set it up again? FUUUUUUUUUUUUUUUUUUUUUUUUUUUUU­UUUU

  • Redneck Much?

  • Thumbup this if Vsauce2 send you here ! :D

  • Vsauce

  • now do that with a 800 lb wheel (force on an everyday break rotar casually stopping) and see if its stops.

  • there are brakes just like that in rollercoasters

  • Vsauce brought me here

  • HEEY

  • I swear I need to put magnets on my speakers.

    Is he whispering. =.=

  • this is going to cause 10x more accidents. It doesn't stop it, it just barely slows it down. Plus the scale of the magnet and the strength would be incredible, so much so that it would interfere with electrical systems. Not to mention expense in comparison to the brakes of today. Useless, ineffective, and pricey.

  • Heyy!

  • Let me guess: the corporations, that make brakes don't apply it because that earn more with the maintenance of the regular brakes? Typical...

  • 1:04

    Sounds like many imports around here!

  • but did you see the gorilla?

  • I'm young and not very good at physics and engineering, but if we're looking to find an alternative energy source to power, for example, cars (alternative to fossil fuels, specifically), why don't we use magnetically propelled and slowed/stopped systems to power our cars? It seems so simple and perfect, can someone tell me why we haven't done this yet?

  • Does the strength of magnetism of the material degrade over time with each use? If this technology were to be used on cars, how long would I need a brake change? Sorry that I'm getting right to the applications and applicability aspects, but it would be good for everyone to know this information. I haven't googled anything, so I await your reply.

  • @mitchrz1 - Neo magnets will last approximately 500 years by most estimates. You should get a few miles on your car before needing to change them, If they used a little ingenuity they could make it so the brakes were moved from car to car as you bought new cars.

  • 1 reason y magnet brakes would be good at dream world australia there is a ride called the giant drop which uses magnets to stop a massive and extremely heavy object 2 a complete stand still in 1 second which is plummeting to the ground

  • king of trolls?

  • stop it with your hand lol

  • @n0rion7 i was bout to comment that

  • vsauce sent me!

  • great comments guys

  • ok... but why not a copper disc and big magnets coming to it...

  • rubber hweheel 0:22 lol

  • @gotcoins I noticed that too.

  • can you microwave it?

  • kewl

  • I m gonna press the spin button.

    -----after a minute-----

    braking smoke, don't breathe this.

  • but is it going to stop the forse of a 2 tone car

  • i don't see how this should be useful to cars... the problem is not that you can't "stop" the wheels, the problem is that the wheels slide if they are stopped too fast.

  • @ChristofFreestyler It wouldn't wear out break pads and discs like they do now.

  • @ChristofFreestyler - Actually this works better than antilock brakes because it never locks up the wheel - it only slows it down and dissipates the energy.

  • @SuperMagnetMan and.. virtually no heat, which also means no fading or glazed pads

  • @SuperMagnetMan Pads would stop it quicker. This would require heaps more room around the wheel. And no where near as powerful to stop a car.

  • @Typho0n86

    You wouldn't do it that way. You would have a copper disc on the main shaft and slide it towards the brake disc.

    And would lock in place when moved into place. The larger surface area will stop it in a few revolutions.

    The problem with this, it only works if it's moving.

  • @JPMorganMustDie Mmmmm and what ParaniodPizza said, with any weight behind it, such as a car, it would have trouble stoping it. ,

  • @Typho0n86

    Magnetic Brakes have been used on Roller Coasters for a long time.

    I would think a roller coaster weighs a tad more than even a Urban Assault Vehicle.

  • @JPMorganMustDie Mmmm but they are on tracks, and you dont want to stop them as fast as you can, cause it would give people wiplash. And thats not what roller coasters are designed for. I thought we were talking about car breaks... If this was so good then Mercedes would be using them... but there not, cause pads are better.

  • @Typho0n86

    There used because there is no maintenance, nothing to break, they can't not work.

    There not used on cars because you still need a alternate brake to brake on a hill.

    With big enough neo magnets and big enough Copper Discs you could slow almost

    anything, too small and the copper would easily reach melting point.

    Although it probably would work, it's just not practical.

  • @JPMorganMustDie HOW DOES MAGNETS WORK

  • @ninjasquidface

    The Magnets induce a current in the Copper Dicc, as if it was wire in a motor. If you short a Motor and try to spin the shaft, it is similar to that. Except the current is in the hundreds of amps creates an Intense magnetic field opposing the Magnetic Field of the Magnet. The faster the disc spins the more heat, current and magnetic field is created. Look up Eddy Currents.

  • @JPMorganMustDie BUT HOW? HOW DOES THEY WORK!

  • @Typho0n86 HOW DOES THEY WORK?

  • @ninjasquidface Derp

  • @Typho0n86 HOW WORK DO MAGNETS?

  • @ninjasquidface Derp-a-derpa

  • @Typho0n86 HOW! HMAGNETSOW

  • @ninjasquidface Apred-a-Pred

  • @Typho0n86 KROW STENGAM OD WOH

  • @ninjasquidface Day Turk Arr Jewbs

  • @Typho0n86 WHY DO MAGNETS DON'T STICK TOGETHER

  • @ninjasquidface TURN THEM AROUND, MAGIC!

  • @Typho0n86 YHW THEY DON'T COME APART

  • @ninjasquidface TEG ANOTHER ENO!!!!

  • @Typho0n86 DS:MGDSADSFML:!!!!!!!!!!!!!!!!­!!!!!!!!!!!!!!!111111111111111­111111111111111111

  • @ninjasquidface BBQ NEKCIHC 0_o-o_0

  • imagine parking too close to another car in a parking lot

  • similar braking system is already used in some trucks and heavy goods vehicles

    Braking using magnetic induction

  • 240p we meet again. 

  • This guy sounds like a salesman, NOPE Chuck Testa

  • the audio is very low....

  • HEYYY

    >:D

  • Well yeah it's easy to stop a tire, it's the 2 ton worth of metal and really fat asses that you should worry about...

  • thumbs up if vsauce brings you here..

  • Roller coasters use magnetic brakes

  • Let's Get you rolling! Come catch a riiiiiiiiiiiiiiiiiiiiiiiiiiiii­ide!

  • @limeroundup lawl scooters the man

  • no more oil brakes no more leakage

  • vsauce2!

  • im sorry did you say hweel?

  • lmao... HEEYY hahahaha

  • So why cant they make cars that run on this already? Oh!! OK!! Cause then the war will be over...

  • Sounds like GW Bush

  • i bet companies wont use these cause then we wouldnt have to replace our brakes anymore

  • @imlostagainWTF Sounds like an add on(with additional costs) if any company would implement it

  • Wheel lol

  • vsauce sent me : )

  • did any one notice how he said wheel?

  • 100-0 in.. death

  • Magnets are magic!

  • Pretty cool lol

  • you just have velocity, you forgot the mass in the equation

  • @Uzerc -so then why are you calling people whores

  • But it doesnt hold the so called break callipre, if you had weight on that object creating inertia. then simply, it would be as affective as using your feet to stop a car

  • his "hayyy!" was "gayyy!"

  • "Heyyyy!!"

    

  • dickbutt

  • @Uzerc How can you lean back? This is so awesome I'm leaning forward!

  • All glory to the hypnovsauce

  • yo

    

  • @Uzerc ha ur talking

  • But can it make a sandwich?!

  • @razorozx It's obviously not female

    

  • I needed to raise my volume for this vid.

  • Heeey!

  • vsauce is invading

  • lol all the people who watch vsauce (like me =D) just give a bunch of views to science vids lol
