The strength and affordability are the two characteristics that make them the most widely used magnets and generate a pull force of over to 850 times its own weight. This means a neodymium magnet weighing 3 grams can generate over 2,500g of pull force, much higher than its previous counterpart .Since the discovery of these rare earth magnets, technological innovation has lead to an increase in demand with manufacturers producing an astonishing 50,000 tonnes every single year. ABOUT USFAQSDELIVERY AND RETURNSCONTACT USHealth and Safety Can a magnet adversely affect my smartphone?Many experts claim small to medium sized magnets does not have any unwanted effects on your smartphone or tablets. Most of devices, especially smart phones and computers, have small magnets inside of them to perform specific functions. However, since large magnets have such a strong magnetic field it is advised to keep them away from your devices.Technical Information How are magnets made?Various types of permanent magnets are made in different ways, but each includes a process of casting, pressing, sintering, compression bonding, injection molding, extrusion and calendaring to ensure quality and strength of every individual magnet.How do these magnets work?There are many explanations to this question, but one of the most profound ones relate to the magnet’s atomic structure. All ferromagnetic materials produce a magnetic field which is very weak. This is generated by the electrons which surround the nuclei of its atoms. These group of atoms are oriented in the same direction and each of these groups are known as a single magnetic domain.Is it possible to block/shield magnetic fields?The magnetic fields penetrate through plastics, aluminum, wood, and even lead just as if it were not there. No material blocks magnetism. Metals that are ferrous, such as iron, nickel or steel can help conduct magnetic fields and magnetism. All magnetic fields search for the shortest route from north to south and a piece of steel can provide a link that makes the journey from north to south far much easier to flow than through the air Are magnets safe for children?It is strongly recommended that no child handles strong magnets without the correct adult supervision. When purchasing this item you agree that we hold no liability for damage or injury that occurs from the use or misuse of this product.PerformanceHow possible is it to increase the strength of my magnet?Once a magnet is completely magnetized, one cannot make it any more powerful since it is already completely ‘saturated’. Adding one magnet to another, such as stacking them, would mean the stacked magnets work as a large magnet and exercise a stronger magnetic power. However, individual magnets cannot be enhanced further.How durable are neodymium magnets?Permanent magnets are known to retain their magnetism for many years when maintained and used in optimal working conditions. For example, it is estimated that a neodymium magnet loses 5% of its magnetism for every 100 years. However, neodymium magnets are known for being very fragile, so it is always a safe bet to avoid clashing magnets together as they may chip.
