Needle for Magnetic Needle Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4639
Jlab Export is a leading Needle for Magnetic Needle Manufacturer,and suppliers in India
Needle for Magnetic Needle (code EL-SLE-4639) is a magnetised needle supplied on its own, without a stand, to fit a magnetic needle stand. Balanced on its pivot, it lines up with the Earth’s magnetic field and shows the north–south direction approximately, so schools use it to replace a needle that has been lost, bent or weakened. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Loose Magnetic Needles?
| Model | Needle | Bearing | Sizes listed |
|---|---|---|---|
| This needle (EL-SLE-4639) | Magnetic needle | Not stated | Confirm with JLab |

Order this needle as a replacement for a needle stand, and confirm the fit with JLab when you enquire. If you need a stated length or a particular bearing — a jewel bearing turns with less friction, a brass cup bearing is the common classroom type — the two listings above give those details.
What Is a Spare Magnetic Needle Used For?
A magnetic needle on a stand is one of the most handled pieces of school physics apparatus: it shows that a freely pivoted magnet settles in the north–south direction (class 6), finds the poles of a bar magnet, and swings when a current flows in a wire above it in Oersted’s experiment (class 10 and class 12). With that much use, needles get knocked off their pivots, bent, mislaid, or weakened by being stored next to strong magnets. A spare needle puts the stand back into service without buying a complete new instrument.
When fitting it, lower the needle gently onto the pivot point so the tip is not blunted, and check that it swings freely and comes to rest in the same direction each time. Keep spare needles away from strong magnets and iron objects in storage.
Frequently Asked Questions
Does this listing include a stand?
No. It covers the needle only. The complete Magnetic Needle on Stand is a separate listing, linked below.
Will it fit my existing stand?
Send the product code or a photo of your stand and the needle length you need, and JLab will confirm the fit before quoting, because this listing does not state the needle length or bearing.
What does the needle indicate?
The direction of the Earth’s magnetic field where it stands, which gives north and south approximately; nearby magnets, iron or a current-carrying wire will also turn it.
How do I know the needle is still well magnetised?
A good needle swings briskly and settles quickly in the same north–south line each time. A needle that wanders, settles slowly or stops in different directions has probably lost magnetism or has a damaged pivot point and should be replaced.
Who makes these needles?
Jain Laboratory Instruments Pvt Ltd (JLab) makes them at its works in Ambala, Haryana, India, and supplies them directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics instruments manufacturer and supplier in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Spare needles are made at JLab’s own works rather than bought from traders, so schools, colleges, dealers and importers can buy them factory-direct alongside the stands they fit; each needle is checked by eye before dispatch. JLab exports worldwide and ships to buyers in every region — for example Samoa in Oceania, Colombia in South America, Egypt in North Africa, Angola in Central Africa and Singapore in Southeast Asia.
Stands and Apparatus That Use a Magnetic Needle
- Magnetic Needle on Stand — the complete needle and stand for showing the Earth’s field direction.
- Magnetic Needle with Stand — a needle on an aluminium pillar with a steel pivot on a plastic base.
- Oersted Apparatus — a pivoted needle inside a frame with terminals, for the effect of a current on a magnet.
- Magnetic Plotting Compass — a cased needle for plotting field lines.
