How do you measure the strength of a magnet?
Magnet grade is a good way to measure the strength of a magnet.
In general, the larger the number, the stronger the magnet.
There are different grades of NdFeb, such as:
What do these numbers mean, and how does the grade relate to the strength of the magnet?
For example, N42 is less magnetic than N52.
This number comes from the maximum energy product of the magnet material and is expressed in MGOe
The pull force of the magnet varies with the grade or number after the "N". The larger the number, the stronger the magnetism.

2.What Grade should I use?
The grade that works best for you depends on your purpose.
If you need high-strength applications in small packages at room temperature, the N52 is the strongest material available.
If you want to strike a balance between strength and cost, the N42 model is the best choice. It has a good balance over a certain temperature range and is affordable.
If you are working at a moderately elevated temperature, about 60°C-80°C, the N42 magnet may actually be stronger than the N52. This is especially true if your magnet has a very thin shape.
For higher temperatures, high temperature resistant grades are recommended.
