This is neodymium magnet, it is the third generation rare earth permanent magnet.
It is the most powerful and strongest magnet in Wrold at present.
Rod magnet is one popular shape of Rare earth magnets and permanent magnets.
It is always manufactured via Cutting, Slicing, Centerless grinding, etc.
Rod magnets have the following important factors such as, Diameter, Height, etc.
The high performance
neodymium magnets that have a magnetic length which is longer than their diameters are wide.
Neodymium rods will give a deeper magnetic field than a circular disc with the same diameter due to the longer lengths. They are used where a small size and maximum power are needed.
Neodymium Magnets exert very high forces and can attract each other through unbelievably large distances making them very popular for a wide range of applications including scientific experiments, packaging, display, furniture and even musical instruments. They also have an immense and unbeatable resistance to being demagnetised, making them ideal for repulsion applications as well as attractive.
