Alnico U-Shaped Magnet
Product Code : LSK-M-11077
Alnico U-Shaped Magnet (SKU LSK-M-11077) is a high-strength permanent magnet with parallel arms separated by an 18 mm centre gap, giving a defined space in which to probe or use the field. Physics teachers in schools, junior colleges and polytechnics use it for pole, field and force-on-conductor demonstrations. As a science apparatus manufacturer in India, Science Lab Supplies produces it at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and deals directly with schools, colleges, tender contractors and distributors.
Specifications
The magnet is alnico, an aluminium-nickel-cobalt alloy with iron, specified with high strength and long-lasting magnetism and supplied with a keeper. The gap between the arms is 18 mm, and four lengths are listed, 50, 75, 100 and 150 mm, all with an 11 x 8 mm section.

Applications and Experiments for the Alnico U-Shaped Magnet
The fixed 18 mm gap makes this magnet useful when something must sit inside the field: a current-carrying wire, a small coil or a compass needle. It supports school physics lab equipment lists for Class 10 and 12, plus introductory electromagnetism practicals in B.Sc. and diploma courses.
- Class 10 physics: force on a conductor carrying current between the arms.
- Class 12 physics: fields of permanent magnets and the idea of a uniform field region.
- Class 10 and 12: moving a wire or coil through the gap to show induced current on a galvanometer.
- Middle school science: attraction and pole identification.
Standard Scope of Supply
The Alnico U-Shaped Magnet is supplied with its keeper in the length you select, 50, 75, 100 or 150 mm. Galvanometers, conductors, compasses and power sources used in the experiments above are separate apparatus and can be requested on the same enquiry if needed.
Packing, MOQ and Lead Time
There is no need to order in bulk: request a price for one magnet or for a full physics lab across several lengths. Our quotation spells out packing, delivery time and cost for that quantity, and any related apparatus you list is priced alongside it.
With an Importer-Exporter Code in place, Science Lab Supplies can ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. For a quote, use our contact page; to combine items, add them to the enquiry cart; tender buyers can start at the lab tender page.
Frequently Asked Questions
What is the gap between the arms of the Alnico U-Shaped Magnet?
The centre gap is 18 mm on the listed sizes. That leaves room to hold a wire, a small coil or a compass between the poles during an experiment.
Which lengths are available?
Four lengths are listed: 50, 75, 100 and 150 mm, each with an 11 x 8 mm section. Longer magnets give more room to handle; state your size and quantity when you enquire.
How does it compare with the chrome steel U-shaped magnet?
The alnico model is specified with high strength and lasting magnetism, while the chrome steel U-shaped magnet in the same range has moderate strength and a marked north pole.
Is Science Lab Supplies the manufacturer or a trader?
Manufacturer. The alnico U magnets are made in the company's Saha, Ambala factory in India, and you receive your quotation from the producer rather than from an intermediary.
