Electromagnetic Levitation SystemThe
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.
The magnetic levitation system is available as a kit or fully assembled unit. The system works with both sphere and disc magnets (or three disc magnets stuck together). This is a great science fair project for students. It is recommended for ages 12 and up.
