Magnets U-Shaped Alnico Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4637
Jlab Export is a leading Magnets U-Shaped Alnico Manufacturer,and suppliers in India
Magnets U-Shaped Alnico (code EL-SLE-4637) are U-shaped Alnico magnets of superior magnetic strength, with clearly marked north and south poles and supplied with keepers. They give a strong field between the two pole ends for motor-effect, induction and magnetic-field practicals in school and college physics labs. They are made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab U-Shaped and Horseshoe Magnets?
| Model | Shape | Material and strength | Other listed details |
|---|---|---|---|
| This magnet (EL-SLE-4637) | U-shaped | Alnico, superior | 50 mm, 100 mm and a middle length; both poles marked; with keepers |
| U-Shape Magnet (Alnico) | U-shaped | Alnico, superior | With keeper; north pole marked with a small white circle; six sizes from 15 x 6 x 75 mm to 15 x 8 x 150 mm |
| U-Shaped Magnets Chrome Steel | U-shaped | Chrome steel, moderate | 50, 75 and 100 mm; poles marked; with keepers |
| Magnets Horse Shoe Alnico | Horseshoe | Alnico, strong | Painted red; poles indicated; with keepers |
Choose this magnet when you want the stronger Alnico material with both poles marked in a short or medium length. The U-Shape Magnet (Alnico) listing gives full cross-section sizes up to 150 mm long, the chrome steel version, of moderate strength, covers routine class sets, and the horseshoe magnet suits practical sheets that ask for that shape.
What Is an Alnico U-Shaped Magnet Used For?
Alnico is a permanent-magnet alloy of aluminium, nickel and cobalt with iron, and in a U shape it puts a strong, concentrated field across the gap between the two pole ends. That gap is the working space for class 10 and class 12 electromagnetism practicals: lay a current-carrying wire between the poles and it is pushed sideways, showing the motor effect and Fleming’s left-hand rule; move a wire or small coil through the gap with a galvanometer connected and the needle shows an induced current, which is stronger with a stronger magnet. The marked poles let students record the field direction correctly, and iron filings on a card over the poles show the field pattern.
Alnico is strong but can be weakened by a strong opposing magnet, by knocks or by being stored with its poles open, so always replace the keeper across the pole ends after use and store the magnets apart from other magnets.
What to Specify When Ordering
- Length — 50 mm, 100 mm or the middle size, with the quantity of each; ask JLab to confirm the middle length.
- Material — this Alnico magnet (superior strength) or the chrome steel version (moderate strength).
- Quantity — minimum 10 magnets per order.
- Accessories — a galvanometer, iron filings or a current balance kit for the same practical.
Frequently Asked Questions
What lengths are available?
50 mm and 100 mm, with a middle length in between. The listing’s figure for the middle size is unclear, so state the length you need and JLab will confirm it on the quotation.
Why is Alnico stronger than chrome steel?
Alnico is a purpose-made magnet alloy of aluminium, nickel and cobalt with iron, and JLab lists these magnets as superior in strength, while its chrome steel U-shaped magnets are listed as moderate.
Are keepers included, and why do they matter?
Yes, keepers are supplied. Alnico can lose some magnetism if it is left with its poles open or placed against another strong magnet, so the keeper should go back across the poles whenever the magnet is put away.
Are the poles marked?
Yes, both the north and the south pole are clearly marked on each magnet.
Which practicals benefit most from a strong U-shaped magnet?
Experiments where the field strength shows in the result, such as the force on a current-carrying wire and inducing a current in a moving wire or coil, where a stronger field gives a larger, easier-to-see effect.
Who makes these Alnico magnets?
Jain Laboratory Instruments Pvt Ltd (JLab) manufactures them at its works in Ambala, Haryana, India, and quotes for them directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an educational physics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road in Ambala, Haryana. These Alnico magnets come from JLab’s own works, not from a trader, so schools, colleges, dealers and importers get them factory-direct; every magnet is inspected by eye before it leaves, and repeat orders and spare keepers are handled by the manufacturer itself. JLab exports worldwide and ships to buyers in every region — for example Lithuania in Northern Europe, Cambodia in Southeast Asia, Kazakhstan in Central Asia, the USA in North America and Turkey in the Middle East.
Apparatus for Electromagnetism Practicals
- Galvanometer — detects the small currents induced when a wire or coil moves between the poles.
- Magnets Bar Alnico — strong Alnico bar magnets supplied in pairs with keepers.
- Current Balance Kit — for measuring the force on a current-carrying wire in a magnetic field.
- Iron Filling — a shaker-lid jar of filings for showing the field between the poles.
