Magnetic Needle
Product Code : LSK-PL-10347
Magnetic Needle (SKU LSK-PL-10347) is a pivoted magnetic needle on a stand, the classic apparatus for showing magnetic fields, the Earth’s magnetism and how a compass works. Its 70 mm red and blue pointer swings freely in a horizontal plane and settles along the local field lines. It is used from middle school to senior secondary physics. Science Lab Supplies produces the needle in its own manufacturing unit at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and supplies schools, colleges, tender contractors and distributors directly.
Specifications
A balanced two-tone needle, red at one end and blue at the other, rests on a sharp steel pivot at the top of a vertical pillar. The pillar stands on a stable circular aluminium base 30 mm across, and the assembly is 60 mm high, with a 70 mm needle 4 mm thick.

Applications and Experiments for the Magnetic Needle
Because the needle turns freely in a horizontal plane, it lines up with whatever magnetic field surrounds it: the Earth’s field on an empty bench, or the field of a magnet or current-carrying wire placed nearby. That makes it a simple, reusable item in school physics lab equipment in India.
- Middle-school science, magnets: a freely pivoted magnet settles in a north–south direction.
- NCERT Class 10 science, magnetic effects of electric current: needle deflection near a current-carrying wire.
- Class 12 physics, magnetism and matter: the Earth’s magnetic field and compass principles.
- Mapping the field around a bar magnet by moving the needle to different positions.
Standard Scope of Supply
Each Magnetic Needle comes as a single unit: the 70 mm two-tone needle on its steel pivot, the vertical pillar and the 30 mm circular aluminium base. Magnets or compasses for companion experiments are separate items and can be added to the quotation.
Packing, MOQ and Lead Time
Needles can be quoted one at a time or in class sets so each student group has its own. The quotation confirms packing, delivery time and price for the number you ask for, and magnets or compasses for the same lessons can be quoted with them.
Science Lab Supplies, a registered exporter holding an Importer-Exporter Code, is able to ship to buyers in Saudi Arabia, Oman, the Philippines, Nepal, Bangladesh and Zambia. Get in touch through the contact page, place items in the enquiry cart, or review the lab tender page before a tender.
Frequently Asked Questions
What is the Magnetic Needle used for?
It demonstrates magnetic fields, the Earth’s magnetism and the principle of the compass. The pivoted needle turns freely in a horizontal plane and aligns itself with the local magnetic field lines.
What are the dimensions?
The needle is 70 mm long and 4 mm thick, the circular aluminium base is 30 mm in diameter, and the overall height of the stand is 60 mm.
Why is the needle coloured red and blue?
The two-tone finish lets students see at a glance which end of the needle is which, so they can record the direction in which it settles near a magnet or wire.
Does Science Lab Supplies manufacture the needle?
Yes, it is a manufacturer rather than a trader. The needle is made at its own works in Saha, Ambala, and your quotation comes from that facility.
