China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Bar magnet is a permanent magnet with a rectangular or bar shape, usually with opposite poles (north pole and south pole) at each end, and a detailed introduction about its type is given today.
Bar magnet material type;
Mainly neodymium bar magnets, ceramic bar magnets, samarium cobalt bar magnets, flexible rubber bar magnets, alnico bar magnets, you can choose the right material according to your project's requirements for magnetism, temperature resistance.
Bar magnet shape type;
There are mainly standard bar magnets, bar magnets with through holes, bar magnets with countersunk holes, bar magnets with grooves, and some specially processed bar magnets.
Standard neodymium bar magnets, length, width, height, plating, grade, etc. can be customized.
Types of bar magnet magnetization direction;
There are magnetization along the length direction, magnetization along the width direction, magnetization along the thickness direction, and some of the materials can also be multi-pole magnetization.

The type of bar magnet depends on the material, construction, application and magnetization method. Choosing the right type requires a combination of magnetic strength, environment and cost. For example, NdFeB is suitable for high performance needs, while ferrite is suitable for low cost scenarios, and samarium cobalt is suitable for high temperature applications above 250°C that require certain magnetic properties.
