Magnetic needle on stand
Whatsapp Order
 Product Description
The Magnetic Needle on Stand is a precision laboratory instrument used primarily for demonstrating magnetic fields and directionality in physics and earth science education. It consists of a finely balanced magnetic needle mounted on a stable stand, allowing free rotation to align with the Earth’s magnetic field or an applied magnetic field. Constructed from magnetized metal, the needle provides a clear and accurate indication of magnetic north or the direction of a nearby magnetic field source. The sturdy stand ensures stability during demonstrations or experiments, making it an essential tool for classroom experiments, compass demonstrations, and magnetism studies.
