@ciockyvisa No actually, the steel will react with the magnetic field and the magnet will try to attach itself to the steel. in order for eddy currents to be made the material must be non ferromagnetic much like aluminum or copper. If you want a faster brake time then the thickness of the material must be increased as well as the diameter of the disk. In fact ill upload a prototype friends and i made for our senior design project. i think you will like it. keep your eye open for it.
hmm....i had a question in my mind after seeing your video.
can the disk from hard disk can also run to create eddy current when the magnet reaches near to it ?i need to know because i am goin to build this brake for my school science project
Sorry I didnt answer any sooner. The disk is aluminum non ferromagnetic it does not react to magnetic fields. However when it spins and you have a magnetic field exposed to it, eddy currents are created on the disk. These eddies create a secondary magnetic field on the disk which opposes the motion of the disk forcing it to slow down.
do you have any physical explenation for that? im really intrested in how that is possible, how come the magnet doesnt attach to disc? or does the disc have to be magnetised?
I guess a Horse Shoe Magnet would be far more effective, is it so?

Finally, a video with magnets and a wheel that doesn't claim to be the invention of perpetual motion \o/ \o/ \o/

Copper Disk
You want the Magnetic field to induce a current in disk, the current creates a Megnetic Field opposing the Magnets. The Copper Disk will get RED HOT.
Copper is a better Electrical Conductor.

hello,
nice vid u got, can u tell me if a use a steel disk , does it brake faster?
