Magnetic Needle (Jewel Bearing) – 75mm (KS4+)

The 75mm Magnetic Needle with Jewel Bearing is a precision component designed for accurate investigations into magnetism and magnetic fields in KS4 and post‑16 physics lessons. Its high‑quality construction allows students to observe sensitive and reliable needle movement when exploring magnetic effects.

Fitted with a jewel bearing, the needle rotates smoothly with minimal friction, ensuring quick and precise alignment with magnetic fields. This makes it ideal for demonstrating small field changes and directional effects in controlled classroom experiments.

With a length of 75mm, the magnetic needle is easy to observe during demonstrations while remaining compact enough for individual or small‑group practical work. It is best used in conjunction with a magnetic needle stand for stable, accurate positioning.
