Floating Ring Magnet Apparatus
Product Code : EL-M-10311
Quick answer: The floating ring magnet apparatus shows magnetic repulsion: five ceramic ring magnets of 32 mm external diameter sit on a wooden rod fixed to a base, and when like poles face each other the rings float one above another. The assembled unit stands 150 mm high. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the apparatus is used in teaching
Each ring is a magnet with a north pole on one flat face and a south pole on the other. Threaded on the rod with like faces together, each ring is pushed upward by the one below until the repulsive force balances the weight it carries. The rod stops the rings from flipping over and snapping together, so the balance of forces stays visible.
- Lift the rings off the rod and let students feel attraction and repulsion between two rings held in the hand.
- Replace the rings one at a time, each with the same face downwards, so that like poles face each other.
- Observe the rings floating and measure the gaps between them with a ruler.
- Turn one ring over and replace it; it snaps onto its neighbour, showing attraction between unlike poles.
Students usually notice that the lowest gap is the smallest. The bottom pair of rings must support the weight of all the rings above, so those magnets sit closer together, where the repulsion is stronger; repulsion rises steeply as the distance falls.
Key features
- Five ceramic ring magnets, 32 mm external diameter, sized for a clear floating effect.
- Supplied ready to use: rings, wooden rod and base together.
- Compact 150 mm overall height for a desk or demonstration bench.
- Wooden rod is non-magnetic, so it guides the rings without affecting the field.
- Rings lift off for hand-held attraction and repulsion tests.
