Magnetic Needle on Stand Brass Bearing giant Thermal conductivity rods are commonlyThe 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 magnetised 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
