Magnets Bar Alnico Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4632
Jlab Export is a leading Magnets Bar Alnico Manufacturer,and suppliers in India
Magnets Bar Alnico (code EL-SLE-4632) are strong Alnico bar magnets, supplied in pairs with keepers and with the north pole marked on each bar, used for magnetism experiments in school and college physics. Alnico bars are listed as stronger than chrome steel bars, and the pairs come in 2, 3, 4 and 6 inch lengths. They are made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Bar Magnets?
| Model | Material and strength | Size | Other listed details |
|---|---|---|---|
| These Alnico bars (EL-SLE-4632) | Alnico, strong | 2, 3, 4 or 6 inch length | Pairs with keepers; north pole marked |
| Magnetic Bar Chrome Steel | Chrome steel, moderate | 2, 3, 4 or 6 inch length | Pairs with keepers; painted red and blue |
| Bar Magnet | Alnico | 50 x 16 x 10 mm | Listed as an Alnico bar |
Choose the Alnico pairs when students need a stronger field — for clearer iron-filing patterns or for attraction and repulsion felt at a greater distance — with the north pole already marked. The chrome steel pairs come in the same lengths at moderate strength, and the small Alnico bar suits compact individual kits.
What Are Alnico Bar Magnets Used For?
Alnico is a permanent-magnet alloy made mainly of aluminium, nickel and cobalt with iron, and it gives a noticeably stronger bar than ordinary magnet steel. In the class 6 science chapter on magnets, students use a pair to show that like poles repel and unlike poles attract and that a freely hanging magnet settles north–south. In the class 10 topic of magnetic field lines they map the field with a plotting compass or iron filings, and class 12 physics and college labs use the bars for magnetism and matter experiments. Because the north pole is marked, students can check the compass rule straight away: the north-seeking end of a compass needle points towards the magnet’s south pole.
Strong as it is, Alnico loses magnetism if it is dropped, knocked or heated, or left with like poles pressed together. Store each pair side by side with opposite poles next to each other and the keepers across the ends, and keep them clear of electronic devices and cards with magnetic strips.
What to Specify When Ordering
- Length — 2, 3, 4 or 6 inches; several lengths can be quoted together.
- Quantity — the minimum order is 10 pairs.
- Alternatives — add chrome steel pairs if you want a moderate-strength set alongside the Alnico bars.
- Field-line accessories — iron filings and plotting compasses can be added to the same enquiry.
Frequently Asked Questions
How strong are Alnico bar magnets compared with chrome steel?
Stronger. The listing describes these Alnico bars as superior in strength to chrome steel magnet bars, which makes field patterns and pole effects easier for a class to see.
What lengths are available?
2, 3, 4 and 6 inches, about 51, 76, 102 and 152 mm. Each length is supplied as a pair with keepers.
Is the north pole marked?
Yes. The north pole is indicated on each bar, so students do not need to find it with a compass first.
Why are keepers supplied?
To protect the magnetism. Laid across the ends of a pair stored side by side, the soft-iron keepers give the field a closed path; this matters for Alnico, which can be demagnetised more easily than its strength suggests.
What should an export quotation request include?
The number of pairs in each length, the destination country and port or city, preferred delivery terms such as FOB or CIF, any packing or labelling needs, and the tender reference if one applies.
Who manufactures these magnets?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes them at its works in Ambala, Haryana, India, and quotes for them directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of physics apparatus and science teaching equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The Alnico pairs are produced at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers buy factory-direct; each pair is visually inspected before dispatch, and repeat orders in all four lengths are handled by the manufacturer. JLab is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise). It exports worldwide and can serve buyers in every region, including Algeria in North Africa, Austria in Western Europe, Bolivia in South America, Mexico in North America and Iceland in Northern Europe. Tender details are on the JLab lab tenders page.
