How to calculate the magnetic force of the n52 grade in neodymium magnets n52
The theoretical maximum value of neodymium magnets is 512kj/m3 (64mgoe). At present, most manufacturers of neodymium magnets can produce neodymium magnets n52 magnets. The maximum value of neodymium magnets n52 has reached 90% of the theoretical limit.
The theoretical maximum value of neodymium magnets is 512kj/m3 (64mgoe). At present, most manufacturers of neodymium magnets can produce neodymium magnets n52 magnets. The maximum value of neodymium magnets n52 has reached 90% of the theoretical limit.
So how is the magnetic force of neodymium magnets n52 calculated? In fact, the magnetic force is affected by many factors, but the theoretical value can still be calculated, because neodymium magnets n52 can absorb objects that are more than 600 times its own weight, then we can use this Expanding the inference, the formula for calculating mass is m=ρv, and mass is equal to density multiplied by volume. Then we first need to know the density of neodymium magnets n52, which can be calculated later;
The density of neodymium magnets n52 is basically 7.5g/cm³. After knowing the density, the weight of the magnet can be calculated, which is convenient for evaluating transportation costs and estimating the approximate magnetic force.
Maybe you have a question, is the density of 7.5g/cm³ accurate?
No problem, 7.5 is an approximate value. The following is the density of each grade of neodymium magnets in each series:
N series is generally 7.4~7.6g/cm3
H series is generally 7.5~7.65g/cm3
SH series are generally 7.5~7.65g/cm3
UH series is generally 7.55~7.7g/cm3
EH series is generally 7.6~7.75g/cm3
AH series is generally 7.65~7.8 g/cm3
It can be seen that the higher the magnetic grade of neodymium magnets n52, the higher the density value.
However, the magnetic force calculated by this method is a theoretical value, and the actual measurement is the main one. The above is for reference only.
