Choose this pair when you want chrome steel magnets with keepers in a choice of four lengths. The steel set suits classes that also need iron filings and letter-marked poles, while the Alnico bar is a more compact magnet.
What Are Chrome Steel Bar Magnets Used For?
Bar magnets are the starting point for magnetism in the class 6 science chapter on magnets and return in the class 10 topic of magnetic field lines and in class 12 physics. With a pair, students show that like poles repel and unlike poles attract, find north and south by letting a magnet swing freely, trace the field around the bar with a plotting compass or iron filings, test which materials are magnetic, and magnetise a steel needle by stroking it. The red and blue paint helps tell the two ends apart; confirm which end is north with a compass, whose north-seeking end is drawn towards the magnet’s south pole.
Store the two bars side by side with opposite poles next to each other and the keepers across the ends. The soft-iron keepers complete the magnetic circuit and slow the gradual loss of magnetism. Avoid dropping, hammering or heating the magnets, all of which weaken them, and keep them away from watches, phones and magnetic cards.
What to Specify When Ordering
- Length — 2, 3, 4 or 6 inches; mixed lengths can be quoted together.
- Quantity — the minimum order is 10 pairs; many schools plan one pair per student group.
- Accessories — add plotting compasses, magnetic needles or iron filings for field-line practicals.
Frequently Asked Questions
What lengths are available?
2, 3, 4 and 6 inches, which is about 51, 76, 102 and 152 mm. State the length, or the mix of lengths, in your enquiry.
How are the magnets supplied?
As a pair of chrome steel bars painted red and blue, with keepers. One unit is one pair, and the minimum order is 10 pairs.
What are the keepers for?
Keepers are soft-iron pieces laid across the ends of the two magnets in storage. They complete the magnetic circuit, which helps the bars keep their magnetism between lessons.
How strong are these magnets?
They are listed as moderate strength, made of chrome steel. That suits attraction-and-repulsion and field-plotting work; for a compact alternative, JLab also lists an Alnico bar magnet.
Which end is the north pole?
Use a compass to check: the north-seeking end of the compass needle points to the magnet’s south pole, so the other end of the bar is north. A freely suspended bar also settles with its north pole pointing north.
What details does an export quotation need?
The quantity per length, the destination country and port or city, preferred delivery terms such as FOB or CIF, any packing or labelling instructions, and the tender reference if you are buying against a tender.
Who manufactures these bar magnets?
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 manufacturer of physics and general science teaching equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. These magnets are made at JLab’s own works and not bought in from a trader, so schools, colleges, dealers and importers get them factory-direct; every pair is visually inspected before dispatch, and repeat orders in any of the four lengths come from the manufacturer. JLab exports worldwide and ships to buyers in every region — Algeria in North Africa, Oman in the Middle East, Norway in Northern Europe, Nepal in South Asia and Turkmenistan in Central Asia, for example. Tender buyers can find details on the JLab lab tenders page.
Magnetism Apparatus
- Magnetic Plotting Compass — a needle in a scaled circular case for plotting field lines around the bars.
- Magnetic Needle with Stand — a pivoted steel needle on a stand for showing a magnet’s effect at a distance.
- Ferrite Bar Magnets with North & South — ferrite bars marked north and south, for student demonstrations and plotting.
- Bar Magnets — a plastic-cased pair for attraction and repulsion lessons.
