A Plotting Compass (One Glass Face) is a compact, primarily used in physics and geography classrooms for visualizing magnetic fields. Unlike standard navigational compasses, these are specifically designed for "plotting"—the process of mapping out magnetic field lines around magnets.
Key Specifications
- Dimensions: 25mm in diameter and approximately 6mm thick.
- Construction: Typically features a durable aluminium case with a single glass face to protect the sensitive internal needle from air currents and debris.
- Dial Markings: Includes cardinal directions (N, S, E, W) and principal points to assist in orientation and route plotting.
- Packaging: Sold as a Pack of 10 (Pk10), making it a standard bulk purchase for school laboratories and science departments.
Recommended Applications
- Magnetic Field Mapping: By placing multiple small compasses around a bar magnet, students can trace the direction of magnetic field lines from the North to the South pole.
- Educational Demonstrations: Used by teachers to show the Earth’s rotation axis or basic navigation principles.
- Lightweight Navigation: While primarily for lab use, their compact size makes them a portable backup tool for hobbyists, hikers, or scouts practicing basic map reading.
- Miniature Projects: Ideal for model builders who require tiny, functioning directional indicators in their designs.
