China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Many people know that samarium cobalt is also a type of rare earth magnet, but its magnetic force is weaker than that of neodymium. However, it has much better temperature resistance. If you want to learn about its surface magnetic force and pull strength, please continue reading below.
Surface magnetic flux density of samarium cobalt magnets
In samarium cobalt magnets, surface magnetic flux density is an important parameter for evaluating magnetic strength. The magnitude of surface magnetic flux density directly affects the efficiency and performance of equipment, typically ranging from 1.0T to 1.2T. The following is a summary of some magnetic data for reference only.

Samarium cobalt permanent magnet pull strength;
The pull force refers to the attractive force that a samarium cobalt magnet can generate when it comes into contact with another iron object. It is affected by factors such as the size of the magnet, the surface magnetic flux density, and the material of the object it comes into contact with. It typically ranges from 0.04 kg to 30 kg.
