    I post project of magnetic levitation system.Please see attached image file of the layout.It needs 4 electric magnetic coils to lift up the plate at the corners.If permanent magnets are needed, they can be attached.I will put the weights on the plate and the weight will be varied between 50g and 500g.And I want to control the lifting heights by microcontroller such as ATMEGA series. The heights will be between 0mm and 20mm and should be controlled individually. The size of plate is 200mm * 300mm.And another important matter is very little heat on the magnetic coils.Final products should be:;1. schematic and pcb design files in full2. 1 set of complete set of system.3. 1 set of completely mounted and tested board.4. 5 pcs of bare pcb.Please describe the full experiences of magnetic levitation system.
