With the rapid development of motor industry in China, demand for cold rolled non-oriented electrical steel has increased year by year, according to the current situation, the test results of magnetic properties for cold rolled non-oriented electrical steel are analyzed, including sample preparation equipment, environmental temperature, sample size, sample weight, sample density and test equipment and so on. The results show that with the increase of shear times, mass and density, the iron loss increases, and the magnetic induction decreases; with the increase of ambient temperature, the iron loss and magnetic induction decrease. The analysis of factors affecting the test results of magnetic properties for cold rolled non-oriented electrical steel has great significance to improve the accuracy of test results.
