The rare earth magnets small square is also called neodymium iron boron magnet. It is one of the permanent magnet. The magnet is widely used in many kinds of scenarios. The squareness of the demagnetization curve refers that the material's magnetization curve deviated the ideal rectangle degree. The squareness of the demagnetization curve is also an important factor which could influence the magnetic performance.
There are many factors which could influence the suqareness of the demagnetization curve. One of the important factors is the ingredient of the magnet.The NdFeB magnet is made of neodymium, iron and boron and other elements. The ingredient's composition propotion could influence the squareness of the demagnetization. If you want to increase the squareness of the demagnetization curve, you could increase the neodymium components.
Another factory which could influence the squareness of the demagnetization curve is the production technology. The production process of the neodymium iron boron magnet includes several procedures. From material powder mixing to the magnitization. Every procedure could influence the squreness of the demagnetization curve. If the production procedure is not well controlled, the magnetic domain will not equally distributed. The squreness of the demagnetization curve will be reduced.
Meanwhile, the size and the shape of the magnet will influence the squareness of the demagnetization. The magnet could be machined into different shapes, hydraulic, disc and so on. The squareness of the demagnetization will change along with the magnet shape and size. The big size of rectangle magnet's squareness of the demagnetization curve is smaller than the small round disc magnet.
