A simple instrument based on Earth's magnetic field
How does a compass find direction?
A magnetic compass contains a magnetized pointer that can rotate freely. The needle aligns approximately along the direction of Earth's magnetic field, allowing the user to identify the north-south direction and read the other cardinal points on the dial.

Basic steps for an educational demonstration
Place on a Level Surface
Keep the compass horizontal on a stable surface.
Keep Away from Magnets
Move magnetic objects and strong electrical equipment away from the compass.
Allow the Needle to Settle
Wait until the magnetized pointer stops moving and settles.
Read the Direction
Observe the needle position against the cardinal points marked on the dial.
Identify Other Directions
Use the north-south reference to identify east and west.
Store Carefully
Protect the glass cover and keep the compass away from strong magnetic fields.
Educational and Laboratory Applications
Useful for basic direction and magnetism-related learning
Physics Laboratories
Introduce magnetic needles, magnetic fields and directional alignment.
Geography Lessons
Teach cardinal directions and basic navigation concepts.
Science Demonstrations
Help students observe how a magnetized pointer responds to Earth's magnetic field.
Important Compass Handling Tips
- Keep the compass away from strong magnets and magnetic materials.
- Avoid placing it close to electrical equipment that may affect the needle.
- Use the compass on a stable, level surface for better observation.
- Handle the glass cover carefully to prevent damage.
- Remember that a compass indicates magnetic direction, which may differ from true geographic north.
