Default Hall effect magnetic levitation

Hey guys I was wondering if anyone else is familiar with or has built a hall effect magnetic levitator.

http://amasci.com/maglev/magschem.html
http://www.allelectronics.com/make-a...ENSOR/-/1.html

It seems very simple, but other schematics Ive seen for more stable coils are far more complex. I have one that I made as a kit when I was 16 but it's weak and small. I wanna build one with a large coil and maybe get an inch or more of distance between the magnet being levitated and the hall effect sensor.

Whatcha Think?!

-Tony

Default Re: Hall effect magnetic levitation

It uses hall effect sensors to detect the strength of the magnetic field. The feedback from the sensors is interpreted by the circuit as a relative distance between magnet and coil.

When the magnet gets too far from the coil electricity flows in one direction through the coil to attract the magnet.
When the magnet gets too close to the coil electricity flows in the other direction through the coil to repel the magnet.
This creates a "sweet spot" in with the magnet is confined to.

This link shows a very simple schematic for set ups like these.
