A magnetic needle stand with a plastic base is a simple, non-magnetic laboratory tool designed to support a magnetic needle for demonstrating magnetism and identifying magnetic north. These stands are essential for physics experiments because their non-magnetic construction ensures the stand itself does not interfere with the needle's alignment with magnetic fields.
Key Features
- Non-Magnetic Pillar: Typically made of plastic or non-ferrous materials like aluminium to avoid affecting magnetic readings.
- Pivot Point: Features a carbon steel or sharp metal point at the top of the pillar to allow the magnetic needle to spin with minimal friction.
- Stable Base: A wide plastic base prevents the stand from tipping during demonstrations.
- Height: Standard educational models usually range from approximately 40 mm (1.6 inches) to 115 mm (4.5 inches) in total height
Recomended Needle: JN-P816B
Note: These stands are almost always sold separately from the magnetic needle itself. Ensure you have compatible needles, such as 75 mm or 100 mm versions, for the pivot point.
