Magnetic Needle on Stand Brass Bearing

The Magnetic Needle on Stand Brass Bearing is a traditional tool that allows students to explore magnetism concepts like magnetic field direction, declination, and strength. 

The 75mm needle features a magnetized design that enables it to rotate precisely on a vertically mounted pin attached to a simple stand. With a brass pivot in the shape of a small socket, the needle offers stability and precision on the pin. As one end of the needle aligns with the earth's north magnetic pole, its main purpose is to detect the presence of magnetic fields that may cause it to deviate from its resting position.
