Please visit http://zeltom.com/products/magneticlevitation for more information. The electromagnetic levitation system is available as a kit or fully assembled unit.
The electromagnetic levitation system controls the magnetic field generated by an electromagnet to levitate a small magnet in midair. The small magnet levitates in the air indefinitely without any disturbance. The vertical position of the levitating magnet is measured using a linear Hall effect sensor and the current in the electromagnet is controlled using a digital signal controller. The system has three push buttons to adjust the vertical position of the levitating magnet and to apply a sinusoidal, square or sawtooth reference signal. Both the amplitude and frequency of the reference signal can be adjusted using the push buttons.
