Bar Magnets
Product Code : LSK-PL-10351
Bar Magnets (SKU LSK-PL-10351) are rectangular chrome steel magnets supplied in pairs with keepers, intended for demonstrating magnetic fields. Placed under paper with iron filings or surrounded by plotting compasses, they reveal the field pattern around a bar magnet in school and college physics lessons. This model is not suitable for attraction and repulsion experiments. Each pair is manufactured by Science Lab Supplies in its Plot 448, HSIIDC Industrial Area factory at Saha, Ambala, India, which deals directly with schools, colleges, tender contractors and distributors.
Specifications
Material, shape and pairing of these chrome steel bar magnets are given row by row. In short, each pair consists of two rectangular chrome steel bar magnets with keepers that are placed across the poles in storage, and the set is meant for magnetic field demonstrations rather than pole-to-pole attraction and repulsion work.

Applications and Experiments for the Bar Magnets
These magnets can be used to show and map the magnetic field around a bar magnet: the lines leaving one pole and curving round to the other, and the way field patterns combine when two magnets are set side by side or end to end, within an electricity and magnetism lab kit for schools.
- Middle-school science, magnets: poles and the space around a magnet.
- NCERT Class 10 science, magnetic effects of electric current: drawing field lines of a bar magnet with iron filings or a compass.
- Class 12 physics, magnetism and matter: the bar magnet and its field pattern.
- Neutral-point experiments combining the field of a bar magnet with the Earth’s field, traced with a pivoted Magnetic Needle.
Standard Scope of Supply
Bar Magnets are supplied in pairs, each pair with its keepers. Iron filings, plotting compasses and paper for field mapping can be listed as extra lines on the quotation, so a complete field-plotting set arrives together with the magnets in one delivery.
Packing, MOQ and Lead Time
Whether you want a single pair for the teacher’s desk or a pair for every student group, the quotation will list packing, delivery time and price for that quantity. Compasses and other magnetism items can be added to the same quotation.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code, and so can ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. The number of pairs per lab can be stated on the contact page or entered in the enquiry cart; where buying runs through a tender, the lab tender page explains the steps.
Frequently Asked Questions
Can these Bar Magnets be used for attraction and repulsion experiments?
No, this model is not suitable for attraction/repulsion work; it is intended for demonstrating magnetic fields. For repulsion, the Floating Magnets set of five ceramic ring magnets on a wooden pole can be quoted.
What are the keepers for?
Keepers are placed across the poles when the magnets are put away. Closing the magnetic path in storage helps the magnets hold their magnetism for longer between lessons.
What material are the magnets made from?
They are rectangular bar magnets made of chrome steel. Each pair comes with its keepers, and the set is intended for demonstrating magnetic fields in classroom and laboratory lessons.
Who makes these magnets?
The chrome steel bars are shaped, magnetised and paired with keepers at the Science Lab Supplies factory in Saha, Ambala, India, so the quotation is prepared by the maker rather than by a trading agent.
