Product Code : SCL-POM-11233
The Magnetism Teaching Needle Apparatus is a physics teaching instrument used to demonstrate magnetic direction, compass action and the response of a freely moving magnetized needle to an external magnetic field. It is intended for schools, colleges, STEM laboratories and teachers who require a clear visual aid for introductory magnetism experiments.
Product Description
The apparatus uses a magnetized needle supported on a pivot or low-friction bearing arrangement. When the needle is free to rotate, it responds to the surrounding magnetic field. Students can observe its resting direction and the deflection produced when a permanent magnet, electromagnet or current-carrying conductor is brought nearby.
The raised support improves visibility during classroom demonstrations and allows the needle to rotate without touching the base. The apparatus complements other magnetism laboratory equipment used to teach magnetic poles, field direction, attraction, repulsion and magnetic effects of electric current. Exact construction details must be confirmed from the approved product specification.
Key Features
- Freely rotating needle: Makes changes in magnetic-field direction visible through needle movement.
- Raised teaching format: Helps students observe deflection during group demonstrations.
- Multiple learning applications: Supports lessons on compass action, magnetic poles, attraction, repulsion and field direction.
- Simple manual operation: Requires no electrical supply for basic permanent-magnet demonstrations.
- Reusable laboratory apparatus: Suitable for repeated teacher demonstrations and supervised student practicals.
- Compatible with related equipment: Can be demonstrated near bar magnets, coils and electromagnets.
- Specification-controlled supply: Needle size, material, pivot construction and base dimensions can be confirmed before ordering.

How to Use the Magnetism Teaching Needle Apparatus
- Place the apparatus on a stable, level and non-magnetic table.
- Remove nearby iron objects, magnets and energized electrical equipment.
- Check that the needle can rotate freely without touching the stand or base.
- Allow the needle to settle and note its initial direction.
- Bring one pole of a bar magnet slowly towards the needle.
- Observe and record the direction and amount of needle deflection.
- Repeat the activity with the opposite pole and at different positions.
Safety and handling: Use the apparatus under teacher supervision. Do not bend the needle, press on the pivot or bring powerful magnets into sudden contact with the unit.
Care & Maintenance
- Keep the needle and pivot free from dust, moisture and chemical fumes.
- Handle the unit by its base rather than by the needle or support point.
- Store it away from strong permanent magnets and ferromagnetic objects.
- Check that the needle rotates freely before each classroom activity.

Frequently Asked Questions
What is a Magnetism Teaching Needle Apparatus used for?
It is used to demonstrate magnetic-field direction, compass action and the deflection of a magnetized needle near magnets or electromagnets.
How does the magnetic needle work?
A freely pivoted magnetized needle rotates in response to the magnetic field around it. It settles along the dominant field direction when external interference is minimized.
Does the apparatus require electricity?
No electricity is required for basic experiments with permanent magnets. A separate electrical setup is needed only when studying fields produced by coils or current-carrying conductors.
Can it be used in school physics laboratories?
Yes. Its visible needle movement makes it suitable for introductory magnetism lessons, practical demonstrations and supervised STEM activities.
Can students use it with bar magnets?
Yes. A bar magnet can be moved around the needle to demonstrate field response, magnetic poles, attraction, repulsion and changes in direction.
What specifications should buyers confirm?
Confirm the needle length, magnet material, pivot design, stand height, base material, overall dimensions, packaging and included instructions before ordering.
