Transparent compass Ø 45 mm

Product Code : SCL-EI-10619

The Transparent Compass 45 mm from Lab Glassware Manufacturer, a scientific and educational equipment manufacturer based in Ambala, Haryana, India, since 1982, is a circular magnetic compass used for school physics experiments, magnetism demonstrations, and field-direction observation. It is supplied to schools, colleges, and institutional buyers across India and exported to countries including Bangladesh, Sri Lanka, Nepal, and Bhutan as part of the company's South Asia science-education supply.

Quick answer: The Transparent Compass 45 mm lets students observe how a freely moving magnetic needle aligns with the Earth's magnetic field or with a nearby magnet or current-carrying conductor. Its transparent body makes needle movement easy to view during classroom demonstrations, magnetic field mapping, and supervised STEM magnetism experiments.

Key Features

• 45 mm circular compass suitable for classroom physics and magnetism experiments.
• Transparent body helps students view needle movement and alignment clearly.
• Useful for teaching magnetic north, field direction, poles, and compass behaviour.
• Compact size supports individual student use and group laboratory activities.
• Suitable for school labs, STEM kits, science fairs, and demonstration tables.
• Can be used with bar magnets, horseshoe magnets, coils, wires, and field-mapping sheets.
• Simple, reusable apparatus for supervised educational use.

Applications / Uses

• Observing magnetic north and compass needle alignment.
• Mapping magnetic field direction around bar magnets and horseshoe magnets.
• Demonstrating the effect of current-carrying conductors on a compass needle.
• STEM activities on magnetism, navigation, and field observation.
• School practical work in physics laboratories and science classrooms.

How to Use the Transparent Compass 45 mm

1. Place the compass on a flat, non-magnetic surface.
2. Keep iron objects, steel tools, phones, and strong magnets away unless they are part of the experiment.
3. Wait for the needle to settle before recording the direction.
4. Move a magnet near the compass and observe how the needle changes direction.
5. For field mapping, place the compass at different points around the magnet and mark the needle direction.
6. Return the compass to its storage box after the activity.

Safety note: Do not expose the compass to strong magnets for long periods, as this may affect needle magnetisation and accuracy.

Care & Maintenance

• Store the compass in a dry, dust-free box after use.
• Keep it away from strong magnets, heat, and direct impact.
• Clean the transparent cover with a soft dry cloth only.
• Replace the compass if the needle sticks, becomes loose, or no longer aligns properly.

Building a Magnetism Demonstration Set

The Transparent Compass 45 mm is often used alongside other magnetism-teaching apparatus. For field-mapping experiments, pair it with a Neodymium Bar Magnet or a set of Cylindrical Magnets (One Pair) to trace field lines, and extend the demonstration to electromagnetism with the Magnetic Field Board for Student Transformer, which lets students compare a permanent magnet field with one generated by an electric current.
