Magnetic Needle 75 mm

Product Code : SCL-EI-10633

The 75 mm Magnetic Needle from Lab Glassware Manufacturer is a magnetised pointer engineered for school physics experiments, magnetic field demonstrations, compass studies, and STEM classroom activities. Manufactured and supplied from Ambala, Haryana, India since 1982, Lab Glassware Manufacturer exports magnetism teaching apparatus to schools, colleges, and STEM training institutes across the Balkans, including Serbia, Croatia, Bosnia and Herzegovina, and Montenegro, supporting institutional procurement and export tenders throughout the region.

Quick answer: The 75 mm Magnetic Needle is a classroom pointer used to observe magnetic direction, field response, and compass action — students bring a magnet near the needle, or move the needle around a magnet, to study attraction, repulsion, and field-line direction in supervised school and STEM physics practicals.

Key Features

• 75 mm magnetic needle for classroom magnetism demonstrations.
• Useful for teaching magnetic north, field direction, poles, and compass action.
• Supports experiments with bar magnets, coils, conductors, and field-mapping apparatus.
• Helps students connect magnetic field theory with visible needle deflection.
• Suitable for school physics labs, STEM kits, and teacher demonstrations.
• Reusable apparatus for supervised practical sessions.
• Can be used with related Electronic Instruments current-and-magnetism experiments.

What’s Included

• 1 x Magnetic Needle, 75 mm
• Protective packing for storage and transport
• Optional stand, pivot, base, compass box, magnets, or activity guide — only if specified in the order

Applications / Uses

• Demonstrating magnetic field direction in school physics laboratories.
• Teaching magnetic north, south pole, attraction, and repulsion.
• Observing needle deflection near magnets and current-carrying wires.
• Supporting compass principle demonstrations and field-mapping activities.
• Using in STEM activities on magnetism and basic electromagnetism.
• Pairing with scientific lab products for complete educational laboratory setups.

How to Use the 75 mm Magnetic Needle

1. Place the needle on its compatible pivot, stand, or low-friction support.
2. Keep steel tools, phones, and strong magnets away unless they are part of the experiment.
3. Allow the needle to settle before noting its direction.
4. Bring a magnet near the needle and observe attraction, repulsion, or deflection.
5. Use the needle at different points around a magnet to study field direction.
6. Store the needle safely after the demonstration to prevent bending or demagnetisation.

Safety note: Keep strong magnets away from watches, magnetic cards, phones, pacemakers, and sensitive electronic instruments. Do not heat, strike, or bend the magnetic needle.

Care & Maintenance

• Store the magnetic needle in a dry, labelled box after use.
• Keep it away from moisture, strong impact, and excessive heat.
• Do not expose it to strong opposing magnetic fields for long periods.
• Replace the needle if it is bent, corroded, weakly magnetised, or unable to align properly.

Pairing with Other Magnetism Apparatus

The 75 mm Magnetic Needle works well alongside Lab Glassware Manufacturer’s other magnetism teaching apparatus. Compare its free-pointing behaviour against the Transparent Compass 45 mm, use a Neodymium Bar Magnet as the deflecting field source, or map a fuller field pattern with the Magnetic 3D Field Demonstrator for a more advanced classroom demonstration.

Frequently Asked Questions

What is a 75 mm Magnetic Needle used for?
A 75 mm Magnetic Needle is used to demonstrate magnetic direction, field response, compass action, and needle deflection in school physics experiments.

What does 75 mm refer to?
75 mm refers to the length of the magnetic needle. It gives students a visible pointer for classroom demonstrations and field-direction observations.

Is this magnetic needle suitable for school students?
Yes. It is suitable for supervised school and STEM use when handled carefully and used with compatible magnetism apparatus.

Can it be used for magnetic field mapping?
Yes. Students can place the needle at different points around a magnet to observe field direction and compare magnetic patterns.

Does the needle include a stand or pivot?
The standard listing should be treated as the magnetic needle only unless a stand, pivot, base, or holder is specifically mentioned.

What details should be confirmed before purchase?
Confirm the needle material, polarity marking, pivot type, stand or base inclusion, packaging quantity, and whether accessories are included.
