Ferrite Rings
Product Code : LSK-M-11079
Ferrite Rings (SKU LSK-M-11079) are ring-shaped ferrite magnets with a central hole, listed in five sizes. The hole lets rings be threaded on a rod or dowel, which makes them useful for repulsion and levitation-style demonstrations as well as ordinary attraction work in school science and physics. Science Lab Supplies manufactures them in Saha, Ambala, India, at its HSIIDC Industrial Area plant (Plot 448), supplying schools, colleges, tender contractors and distributors without intermediaries.
Specifications
These are ferrite ring magnets with high coercivity, so they hold their magnetism well in routine use. The material is hard, brittle and economical. Outer diameters range from 18 to 36 mm and thicknesses from 5 to 8 mm across the five listed sizes.

Applications and Experiments for Ferrite Rings
Ring magnets are chosen when a demonstration needs magnets that can slide on a rod: stacked with like poles facing, they float apart and show repulsion clearly. They also serve general attraction work and can be part of an electricity and magnetism lab kit for schools from Class 6 upward.
- Class 6 science: like poles repel, unlike poles attract.
- Floating-magnet demonstrations on a vertical rod.
- Class 10 physics: field patterns around a ring magnet using iron filings.
Standard Scope of Supply
Ferrite Rings are supplied loose as individual ring magnets in the sizes and quantities you specify. A rod or stand for floating demonstrations is not part of this item; the Floating Ring Magnet Apparatus listed below is the ready-made option if you need one.
Packing, MOQ and Lead Time
Whether you need a few rings for one teacher or enough for every lab group, you can ask for a quotation. It will show packing, delivery time and price for that quantity, and other magnets from the range can be priced on the same document.
Science Lab Supplies has an Importer-Exporter Code and is able to ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Tender buyers may prefer the lab tender page; others can use the enquiry cart or reach us from the contact page.
Frequently Asked Questions
What sizes are the Ferrite Rings?
Five sizes are listed by outer diameter and thickness: 18 x 6, 25 x 5, 30 x 5, 32 x 8 and 36 x 8 mm. Tell us the sizes and quantities you need.
How do ferrite rings differ from ferrite discs?
Both are ferrite with high coercivity. Rings have a central hole so they can be threaded on a rod, while the Ferrite Discs in the same range are solid and come in six sizes.
How should students handle the rings?
Ferrite is hard but brittle. Bring rings together slowly and avoid dropping them, since snapping magnets can chip edges; fingers can also be pinched between larger rings.
Is Science Lab Supplies the manufacturer or a trader?
The rings are made by Science Lab Supplies itself, at its factory in Saha, Ambala, India. Buyers therefore receive pricing and delivery terms straight from the manufacturer.
Related Ring and Disc Magnets
These four items from the magnetism range work well alongside ferrite rings. They include a ready-made floating ring demonstration, solid ferrite discs, rectangular ceramic magnets and small neodymium discs, giving students several shapes and materials to compare, and all can be added to the same quotation.
- Floating Ring Magnet Apparatus — five ceramic rings on a wooden rod.
- Ferrite Discs — solid ferrite discs in six sizes.
- Magnadur Magnets (Rectangular Magnet) — ceramic rectangular magnets.
- Neodymium Discs — small, high-power discs.
