Here we focus on the direction of the magnet:
The use of the box is also very wide, many customers after reporting the size and performance of the box, when I asked him
Which of them is the direction of the magnetic field, they said they did not know, it is not clear. I have to know that the direction of the magnetic field is not the same.
There is a difference, and if the direction of the magnetic flux is mistaken, then the magnet made is useless.
For more details on the magnetization direction, please see the figure below.
