China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Mini square magnet usually refers to the smaller size, the shape of a square magnet, widely used in various types of precision equipment, sensors, toys, handicrafts and some small mechanical devices, the following is a more comprehensive knowledge of the mini square magnet introduction.
The accompanying picture shows a 2mm mini square magnet, made of neodymium with a bright nickel coating, tolerance precision.
Mini square magnets in addition to neodymium material, there are 2 other kinds are also used more, distribution is ferrite and samarium cobalt.
Mini square magnets can be processed size
This mainly depends on the magnet manufacturer's production strength, like neodymium iron boron and samarium cobalt material can generally do width 1mm, 2mm. ferrite material 4mm or so is better processing, before the customer has processed 4x4x1mm ceramic ferrite magnets.
Typical application examples of mini square magnets;
Electronic devices: such as TWS headphones, cell phones, magnetic connection accessories, etc.
Toys: for assembling toys and models.
Industrial: for sensors, motors, fixtures, etc.

Advice on buying mini square magnets;
You need to choose the right magnet material and grade according to the specific application, if you need strong magnetic force, neodymium iron boron magnet is the best choice. Size-wise you need to choose the right size according to the actual space. For surface coating, common coatings are nickel, zinc plating, epoxy coating, etc. Generally, just choose nickel, if the environment is harsh, you can consider black epoxy.
If it is used for outdoor or high temperature environment, it is very important to choose materials and coatings with high temperature and corrosion resistance.
For precision applications (e.g. electronics), pay attention to the tolerance and dimensional accuracy of the magnet.
