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 familiar field pattern around a bar magnet in school and college physics lessons. Note that this model is not suitable for attraction and repulsion experiments. Science Lab Supplies makes these magnets in its own factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and supplies them straight to schools, colleges, tender contractors and distributors.
Specifications
Each pair consists of two rectangular bar magnets in chrome steel, supplied with keepers that are placed across the poles when the magnets are stored. The set is specified for magnetic field demonstrations rather than for pole-to-pole attraction and repulsion work.

Applications and Experiments for the Bar Magnets
These magnets are 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. They are a basic part of 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.
Standard Scope of Supply
Bar Magnets are supplied in pairs, each pair with its keepers. Iron filings, plotting compasses and paper for field mapping are not part of this item; they can be listed as optional lines on the quotation so a complete field-plotting set arrives together.
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. For a price, use the contact page or the enquiry cart; for institutional purchasing, see the lab tender page.
Frequently Asked Questions
Can these Bar Magnets be used for attraction and repulsion experiments?
No. The specification states they are not suitable for attraction/repulsion experiments. They are intended for demonstrating magnetic fields; the Magnetic Activity Kit below covers repulsion and levitation.
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?
Science Lab Supplies manufactures them itself in Saha, Ambala, India. Buying from the factory means your quotation is prepared by the maker rather than a trading agent.
