For R&D and quality control of magnetic materials, the PEM-1520EX electromagnet offers a cost-effective magnetic field generation solution. With technical specifications precisely covering common testing scenarios—delivering a magnetic field intensity of 620 mT at a 10 mm air gap—it meets the saturation magnetization requirements of most permanent and soft magnetic materials. The wide operating current range of 0–8 A, combined with a continuously adjustable air gap, allows users to easily construct complete hysteresis loops or magnetization curves. The system seamlessly integrates with specialized testing instruments such as vibrating sample magnetometers, magnetic susceptibility measurement devices, and torque magnetometers. Suitable for applications ranging from basic scientific research to rapid magnetic material testing on industrial production lines, it is a reliable choice for enhancing magnetic characterization capabilities in university laboratories and factory quality control departments.
