Product Information

See what theories your students can deduce about the science behind this simply looking device that effectively detects North magnetic poles. Turn it on and the green LED lights up. Bring a magnet next to the LED and if the magnet is oriented with its north pole touching the white mark, the LED will go out. If it is the opposite pole that is pointing toward the device, the LED will be unaffected. The detector, develpoed by Ralph Fudge, employs a Hall Effect semiconductor that responds to a magnetic field by increasing its output voltage when one pole is brought nearby and reducing its output when the opposite pole is introduced. Includes instructions.
