Magnets, Ring (Product Code: SLE/MG/08) is a pack of ceramic ring magnets used to build floating-magnet sets that demonstrate magnetic repulsion in school physics lessons. Each pack holds 16 rings, and every ring is 27 mm in diameter and 5 mm thick with a 10 mm centre hole, so the magnets slide easily onto a rod or pencil. The pack is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a school laboratory equipment supplier in India.

The classic use is the floating-magnet stack. Thread several rings onto an upright rod or a pencil with like poles facing each other, and each ring hovers above the one below it because the repulsion balances its weight. Students can press the uppermost ring down and feel it spring back, count how the gaps shrink towards the bottom of the stack, and flip one ring over to see it snap onto its neighbour when unlike poles meet.
With 16 rings in a pack, a teacher can build several stacks for group work or keep spares for rings that chip. Ceramic magnets are brittle, so let rings meet gently instead of snapping them together, and store them in a stack with a spacer. The 10 mm hole also makes the rings useful for simple motor and generator models.
Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India, supplies these ceramic ring magnets to schools, colleges, dealers and kit builders. For vendor registration, the supplying company's GSTIN is 06AAECJ8618A1ZT and its LEI is 3358004HRD1JIVXKYX49.
Single packs and larger quantities can be quoted together with rods, stands or other magnetism items. Company details are on our company profile.

How many ring magnets are in one pack of Magnets, Ring?
One pack of Magnets, Ring (SLE/MG/08) contains 16 ceramic ring magnets. That is enough to build several floating-magnet stacks for group work, or one tall stack with spare rings kept aside.
What size are the ceramic ring magnets?
Each magnet in the Magnets, Ring pack measures 27 mm in outer diameter and 5 mm thick, with a 10 mm hole in the centre. The hole lets the rings slide onto a rod or pencil for floating-magnet demonstrations.
How do ring magnets show magnetic repulsion?
When Magnets, Ring are stacked on a rod with like poles facing, each ring floats above the next because repulsion balances gravity. Turning one ring over makes it attract its neighbour instead, showing both effects with the same magnets.
Is a rod or stand included with the ring magnets?
No rod or stand is listed with the Magnets, Ring pack, which is sold as 16 loose ceramic rings. If you need a stand or a complete floating set, ask through our contact page and we will quote suitable items.
Who supplies the Magnets, Ring pack?
The Magnets, Ring pack (SLE/MG/08) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges, dealers and importers in India and international markets.
