Abstract
The goal of this project was to create an electromagnet that adjusts its magnetic field based on the position of an object below it. The sensors are photo-transistors that are triggered by an infrared LED diode. The strength of the magnetic field is adjusted by controlling the current through a system containing an operational amplifier and a transistor. We successfully levitated multiple objects approximately .25-.5 inches below the electromagnet.
