About This Product
The upper rings hang in the air because the repulsion between like poles balances their weight. The apparatus is used to study repulsive magnetic force and the equilibrium between that force and gravity.
Frequently Asked Questions
Why do the rings on the Floating Ring Magnet Apparatus float?
The ferrite rings are magnetised through their faces and stacked with like poles facing, so the repulsion between them balances gravity.
