Neodymium Discs
Product Code : LSK-M-11080
Neodymium Discs (SKU LSK-M-11080) are rare-earth disc magnets that deliver high magnetic power from very small sizes and strongly resist demagnetisation. They let senior school and college physics students run induction and force experiments with compact magnets. Science Lab Supplies is the manufacturer: the discs are produced at its Plot 448 unit in the HSIIDC Industrial Area, Saha, Ambala, India, and quoted from there to schools, colleges, tender contractors and distributors.
Specifications
Each disc is a neodymium magnet with a polished coating, specified for high power relative to its size and high resistance to demagnetisation. Seven sizes are listed, from a 5 x 2 mm disc up to 24 x 10 mm, so labs can choose small discs for models or larger ones for demonstrations.

Applications and Experiments for Neodymium Discs
Neodymium discs are used where a strong field is needed from a tiny magnet, such as dropping a disc through a copper or aluminium tube to show eddy-current braking. They support Class 12 electromagnetic induction, B.Sc. demonstrations and STEM model building within school physics lab equipment sets.
- Class 12 physics: Lenz's law with a disc falling through a metal tube.
- Class 12 physics: inducing a current by moving a disc through a coil connected to a galvanometer.
- Secondary STEM projects: simple motors and models that need compact magnets.
Standard Scope of Supply
Neodymium Discs are supplied as individual coated disc magnets in the sizes you pick from the seven listed and in the quantity you order. Tubes, coils and galvanometers used in the induction experiments are separate apparatus and can be requested on the same enquiry.
Packing, MOQ and Lead Time
You can request pricing for a small pack of discs or a full lab quantity, mixing sizes as needed. Each quotation lists packing, delivery time and price for that order, and as a physics instruments supplier in India we can add related induction apparatus to it.
Through its Importer-Exporter Code, Science Lab Supplies can ship to buyers in South Africa, Qatar, Sri Lanka, Vietnam, Malaysia and Peru. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU).

Frequently Asked Questions
Which sizes of Neodymium Discs are available?
Seven diameter x thickness sizes are listed: 5 x 2, 6 x 3, 10 x 2, 12 x 3, 20 x 3, 24 x 3 and 24 x 10 mm. Sizes can be mixed.
Are neodymium discs safe for school students?
They are suitable for supervised use. Their strength means fingers can be pinched and discs can chip if they collide, and small magnets must be kept away from young children because swallowing them is dangerous.
How do they compare with ferrite discs?
Neodymium discs give high power at small sizes and resist demagnetisation strongly. The Ferrite Discs in the same range are an economical, high-coercivity option that is hard and brittle.
Is Science Lab Supplies the manufacturer or a trader?
These discs are manufactured by Science Lab Supplies. The company operates its own plant in Saha, Ambala, India, and every quotation for them is sent out directly by that plant.
