Super magnets (= neodymium magnets) are practical and dangerous. Their forces can cause bruises and even broken bones. They produce sparks (= dangerous ignition sources) when they come into contact with each other, and they can effortlessly shoot through glass vessels (see minivideo in attachment). The latter happened as a laboratory accident in HC1: To retain tiny amounts of non-reacted iron, a person had moved a supermagnet towards the reaction flask. The magnet unexpectedly accelerated and crashed the flask. The 2L reaction mixture splashed in all directions, it also hit the user himself. He was very lucky, no injuries, no ignition of the solvent. But you can't always hope for such luck; it's just a matter of time. Safety Officers: Please thematise it! And in this context: Never attach these super magnets to the fume hoods; they have been proven to interfere with exhaust air control.
Safety instructions for neodymium magnets: Please read the safety instruction before using the neodymium magnets.
