Simple Magnetic Levitation.

Magnetic levitation using opamp LM358, mosfet IRFZ44 and Linear Hall sensor. Coil is made using 28SWG and has approximately 12ohms of resistance.  Iron core is only 70% of the coil length, this prevents magnet getting attracted to iron core and damaging hall sensor accidentally.

Here's the link to the original project. I modified according to parts available in my junk box.
