U-Shaped Magnets Chrome Steel Manufacturer,Supplier and Exporter in India

Product Code : EL-SLE-4636
Jlab Export is a leading U-Shaped Magnets Chrome Steel Manufacturer,and suppliers in India

U-Shaped Magnets Chrome Steel (code EL-SLE-4636) are U-shaped permanent magnets made of chrome steel, of moderate magnetic strength, with the north and south poles clearly marked and supplied with keepers. Physics teachers use them to show the field between two poles, the force on a current-carrying wire and electromagnetic induction. 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?

Pick this chrome steel magnet for class sets where three lengths, marked poles and keepers matter more than maximum field strength. Choose the Alnico U-shaped magnet when a stronger field is needed in the same shape, or one of the horseshoe magnets if your practical sheet calls for that form.

What Is a U-Shaped Magnet Used For?

A U-shaped magnet is a bar magnet bent so that its north and south poles face each other across a gap, which concentrates the magnetic field where students can reach it. In class 10 and class 12 physics a straight wire or a small coil is placed in that gap: pass a current and the wire moves sideways (the motor effect, predicted by Fleming’s left-hand rule), or move the wire through the gap and a galvanometer shows an induced current. Younger classes use the same magnet to show that both poles attract iron, to lift pins and paper clips, and to draw the field pattern with iron filings on a card. Because the poles are marked, students can check the field direction with a plotting compass rather than guessing which end is north.

Put the keeper across the pole ends whenever the magnet is stored. The soft-iron keeper closes the magnetic path, which helps a steel magnet hold its magnetism; dropping, hammering or heating it has the opposite effect. Keep magnets away from mobile phones and cards with magnetic strips.

What to Specify When Ordering

• Length — 50 mm, 75 mm or 100 mm, with the quantity of each.
• Material — this chrome steel magnet (moderate strength) or the Alnico version (superior strength).
• Quantity — the minimum order is 10 magnets; add spares for class sets.
• Accessories — plotting compasses, iron filings or a current balance kit can be quoted in the same enquiry.

Frequently Asked Questions

Which lengths can I order?
50 mm, 75 mm and 100 mm. The listing gives no other dimensions, so ask JLab if you need the gap width or the arm cross-section.

Are keepers included?
Yes, the magnets are supplied with keepers. Leave the keeper across the poles in storage; it closes the magnetic circuit and slows the loss of magnetism.

How are the poles identified?
The north and south poles are clearly marked on each magnet, so students can label field diagrams and confirm the direction with a compass.

What is the difference between a U-shaped and a horseshoe magnet?
Both bring the two poles side by side. A U-shaped magnet has straight, parallel arms, while a horseshoe magnet curves round so the pole ends sit closer together; either works for motor-effect and induction practicals.

Should I choose chrome steel or Alnico?
Chrome steel is listed as moderate strength and suits everyday class experiments. The Alnico U-shaped magnet is listed with superior strength for demonstrations where a stronger field helps.

What should an export enquiry include?
The quantity in each length, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling needs and, for tenders, the tender reference.

Who makes these magnets?
Jain Laboratory Instruments Pvt Ltd (JLab), at its works in Ambala, Haryana, India. Quotations come directly from the manufacturer.

OEM Manufacturer

JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of physics and school science lab equipment in India, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. The U-shaped magnets are produced in JLab’s own works instead of being sourced from a trader, so schools, colleges, dealers and importers buy direct from the factory, each magnet is looked over before it is packed, and repeat orders and replacement keepers come from the maker. The company is registered as a manufacturing enterprise under MSME Udyam registration UDYAM-HR-01-0003849 and holds Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example Mexico in North America, Botswana in Southern Africa, DR Congo in Central Africa, Afghanistan in South Asia and Malaysia in Southeast Asia. Tender buyers can find details on the JLab lab tenders page.

Magnetism and Electromagnetism Items

• Current Balance Kit — magnet pairs, a straw balance and circuit wire on a wooden base, for measuring the force on a current.
• Electromagnetic Induction — a wall chart showing how a changing magnetic field produces a current.
• Iron Filling — filings in a shaker-lid jar for showing the field between the poles.
• Magnetic Plotting Compass — a small compass with a printed scale for tracing field lines.
