How much worse is the magnetic performance of n35 than n38?

N35 and N38 are the 2 most commonly used grades of NdFeB magnets, both with a maximum temperature resistance of 80°C. Let's compare the difference in their magnetic properties.

First, let's take a look at the main magnetic parameters of these two grades:

N35: Maximum magnetic energy product (BHmax): 33-35 MGOe, remanent magnetization (Br): 11800-12200 Gauss

N38: Maximum magnetic energy product (BHmax): 36-38 MGOe, remanent magnetization (Br): 12200-12600 Gauss

From these data, it can be seen that the magnetic properties of N38 are slightly higher than those of N35.Taking the median value, the magnetic energy product of N38 is about 8.6% higher than that of N35.The remanent magnetization of N38 is about 3.3% higher than that of N35.

This means that N38 magnets can produce a stronger magnetic force for the same volume.

The picture shows N38 grade ring neodymium magnets.

Suppose we have two magnets of the same size, one with N35 rating and the other with N38 rating, if the N35 magnet can pick up a 10 kg weight, then theoretically the N38 magnet may be able to pick up about 10.3-10.8 kg.

N38 magnets can be slightly smaller than N35 magnets if they need to produce the same suction force. For example, if a 1 cubic centimeter N35 magnet produces a particular suction force, then an N38 magnet of about 0.92-0.93 cubic centimeters would produce the same suction force.

However, for many everyday applications, the difference may not be significant, For some high-precision applications, the effect is still significant, and the choice often depends on specific needs and cost considerations.
