What are the effects of object magnetism on the accuracy of Electronic Balance weighing?

With the continuous development of science and technology, electronic balances are widely used in various industries. In recent years, electronic balances have been used in the research of value transfer and sample analysis of weights, but in the daily application of electronic balances, there are many factors that affect the weighing errors of electronic balances, but most people are not interested in magnetic electronic balances. The influence of accuracy is not well understood, and it is often ignored in practical work applications, which in turn affects the accuracy of the weighing results of electronic balances. This article will make a preliminary analysis of the influence of the magnetic properties of objects on the weighing accuracy of electronic balances from both theoretical and practical parts. JJG99-2006 "Weight Verification Regulations" is the first time to include the magnetic detection of weights into the detection requirements, which is a breakthrough. Why should this test item be added? How does the magnetism of objects affect daily detection and chemical analysis?
