Neodymium sphere magnets are excellent electrical and magnetic devices to use as a tool or toy. The best part is that they are safe to use even for a child. To keep your children safe, you need to follow the safety guidelines provided with the product, which can be found on the Neodymium website.
Wear protective gloves when dealing with large neodymium sphere magnets. The stronger and bigger the magnet, the greater the potential for serious injury. Always use the magnetic spheres in large plastic tubes when not in operation.
When choosing what size of the Neodymium sphere that you want to purchase, you will need to consider the size of the area in which the product will be used. Keep in mind that larger magnets tend to produce a more powerful electrical current than smaller ones. Also keep in mind that the longer the Neodymium spheres are stored, the harder it will be for them to pick up power and become strong enough to use as a tool. Smaller neodymium spheres are great to have around the house to provide an extra magnetic field to a room where there is little natural electrical current.
