Why can't use surface magnetism (surface Gauss value) to determine magnetic properties, but can only be a basic reference?

Because the surface Gauss value is the value measured by the Gauss meter in contact with a certain point on the surface of the product, the measurement point does not cover the entire surface of the product, so it is incorrect to use the value of a certain point to measure the value of the entire surface. And each Gauss meter has an error of about 2%. At the same time, we will definitely have measurement errors in the measurement process, because it is impossible to find two completely coincident points on the same product. Therefore, the surface magnetism can only be used as a basic reference and cannot be used to determine the performance of the product. Usually, we use the magnetic flux/moment value to determine whether the performance of the product is qualified.
