Mini Neodymium Magnet - Powerful - 10mm x 10mm

For such a tiny magnet it really has some grunt! This neodymium rare earth magnet measures just 10mm in diameter but has an impressive pull strength of almost 3kg. Perfect for demonstrating that size is not always the best indicator of magnetic strength. Works well with our magnetic putty.

Age: 12 + with adult supervision. This magnet is not a toy and is not intended for use by young children.

Neodymium magnets are the strongest type of permanent magnets. They are made from a mix (alloys) of rare earth elements: neodymium, iron and boron (Nd2Fe14B).Surprise your students and compare this strong magnet with the strength of other larger magnets like ferrite and alnicos. Students will invariably expect the smallest magnet to be the weakest. One way to test magnet strength is to stick the magnet to a metal slinky, hold the magnet and lift. The more metal coils that can be lifted by the magnet, the stronger the magnet. This mini magnet can lift the slinky clean of the table or floor. Not bad!Rare earth magnets are brittle and can chip or break when dropped on a hard surface or allowed to smash together with another magnet or a piece of metal. We need to remind you to handle them with care and keep these magnets away for computers, videotapes, credit cards and young children. They can leap together from a distance and pinch fingers or anything else between them.

CHOKING HAZARD Small parts not suitable for children under 3 years. Should a child or any person ingest magnets, seek medical help immediately. NO LOOSE METAL OBJECTS Do not store or handle magnets in proximity to iron, steel or other ferrous materials or items. Serious injury or property damage may result. NO PACEMAKERSNO METALLIC IMPLANTSNO NEUROSTIMULATORSPersons with pacemakers, metallic implants or neurostimulators must not handle magnets. Serious injury may result.RISK OF DATA LOSS Permanent magnetic fields may corrupt, degauss or destroy data stored in a magnetic state. This includes floppy disks, hard drives and credit cards.
