Magnetic Needle 75 mm Manufacturer,Supplier and Exporter in India

Product Code : SCL-EI-10633

The 75 mm Magnetic Needle is a magnetised pointer used for school physics experiments, magnetic field demonstrations, compass studies, and STEM classroom activities. It is intended for students, teachers, laboratory technicians, and educational institutions that need a simple visual apparatus for observing magnetic direction and field behaviour.

Product Description

The 75 mm Magnetic Needle helps students observe how a magnetised needle aligns with the Earth’s magnetic field or responds to nearby magnets and current-carrying conductors. It is commonly used in lessons on magnetic poles, field direction, magnetic induction, and compass principles.

This product is suitable for Physics Lab Equipment, school science laboratories, magnetism kits, and STEM classrooms. It can also be supplied with compatible General Lab Equipment for complete laboratory setups. The final pivot type, material, polarity marking, and mounting arrangement should be confirmed before publication.

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.

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 needle material, polarity marking, pivot type, stand or base inclusion, packaging quantity, and whether accessories are included.
