Customer Reviews


5 star rating  Neodymium Disc Magnet
George Heys from Australia, NSW, Harden
The magnets exceeded my expectations. Delivery also was much sooner than expected. As a retired science teacher I am still involved in school-related activities. These magnets make the concept of magnetic field very real and quite dramatically tangible. I have used two of the discs to make a very powerful horseshoe magnet which powers a nice little model electric motor. The strength of the little magnets is such that precautions must be taken - e.g. not to erase bank cards in a wallet. For children care must be observed not to pinch fingers. For senior science students the link with the periodic table and electron configuration of the rare earth elements is nicely illustrated. Thank you for making this product available!
