China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Magnets are common items in our daily lives, from refrigerator stickers to high-end aerospace applications. However, many of you may have encountered the phenomenon of magnets losing some of their magnetic properties after being dropped, what's going on? The article will explain.
Primary cause - physical damage leading to weakened magnetism
When a magnet is dropped from a high place, especially onto a hard surface, it can be subjected to a violent impact. This impact not only causes the magnet to crack or break, but also affects its internal structure. The inside of a magnet is made up of many tiny magnetic domains that, when undisturbed, are all aligned in the same direction, creating the magnet's magnetic properties. When the magnet is subjected to a violent shock, the alignment of these domains is disturbed, resulting in a weakening of the magnet's overall magnetic properties.

Not all magnets lose their magnetism when dropped
Hard magnetic materials (e.g., neodymium magnets) typically have a greater ability to retain their magnetic properties due to their high coercivity, but they are also more brittle and susceptible to loss of magnetic properties due to mechanical damage. In contrast, soft magnetic materials (injection molded magnets, flexible rubber ferrites) are less magnetic, but they are usually more resistant to physical shock and less likely to lose their magnetism.
In order to prevent magnets from losing their magnetic properties due to dropping, the most effective measure is to handle them with care. Avoid placing magnets in locations where they can be easily dropped and handle them gently during handling. In addition, keeping magnets away from hot environments and avoiding prolonged exposure to strong magnetic fields can also reduce the risk of magnetic loss. For those magnets that have lost their magnetic properties, they can be re-magnetized with specialized equipment, but this method is not applicable to all types of magnets.
In short, the phenomenon of magnets losing their magnetic properties after being dropped is mainly due to physical damage, and internal structural changes.
