Levitating Digital Scale

Posted March 13, 2012 by Chris

“The battery-powered Levitating Digital Scale electromagnetically levitates a load platform, and uses a linear hall-effect sensor to measure the magnetic field strength to determine the weight of the platform. The levitating platform is embedded with a permanent magnet that opposes the magnetic field of a solenoid (the electromagnet). When a load is placed on the platform, the levitating platform will settle to a new height.”
