Pair of Bar Magnets with Iron Filings
Product Code : SCL-PL-12404
Pair of Bar Magnets with Iron Filings (SKU SCL-PL-12404) combines two steel bar magnets, 150 x 12 x 5 mm with clearly marked poles, and 500 g of iron filings for mapping magnetic field lines. It supports magnetism lessons from middle school to Class 12 and introductory college physics. Science Lab Supplies is the manufacturer, producing the set at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and it quotes schools, colleges, tender contractors and distributors directly.
Specifications
Each magnet is a straight steel bar of 150 x 12 x 5 mm with its north and south poles clearly marked, so pole-to-pole experiments can be set up without guesswork. The 500 g of iron filings, sprinkled around the magnets, line up along the magnetic force and reveal the field pattern.

Applications and Experiments for the Bar Magnets and Iron Filings
Placing a sheet of paper or glass over the magnets and sprinkling filings on top shows the field of a single bar, of like poles facing each other and of unlike poles attracting. Students can then sketch the pattern and compare it with a plotting-compass map of the same field.
- Class 6 science (NCERT): poles of a magnet, attraction and repulsion.
- Class 10 science (NCERT): magnetic field lines around a bar magnet.
- Class 12 physics: the bar magnet as an equivalent solenoid and its field pattern.
Standard Scope of Supply
The set contains two steel bar magnets of 150 x 12 x 5 mm with marked north and south poles, and 500 g of iron filings. A sheet of paper or glass for the filing pattern and a plotting compass are not included and can be quoted separately.
Packing, MOQ and Lead Time
Quotations are available for a single set or for enough sets for every group in a class, with Science Lab Supplies stating the packing, delivery time and price for that quantity. Compasses and other items for an electricity and magnetism lab kit for schools can be added.

Frequently Asked Questions
What size are the bar magnets?
Each of the two magnets is a straight steel bar measuring 150 x 12 x 5 mm, with the north and south poles clearly marked so students can identify them immediately.
How much iron filings come with the pair?
The set includes 500 g of iron filings. Sprinkled over paper placed on the magnets, they line up along the field and show the pattern of magnetic field lines.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures this magnet set rather than trading it. Its factory in Saha, Ambala, India, produces the set and issues quotations to buyers directly.
How should the magnets and filings be stored?
Store the two bars side by side with opposite poles together, away from heat and hard knocks, and keep the iron filings in a closed container so they stay dry and clean.
