Overview

Magnetic Materials Measuring Laboratory is responsible for research, establishment, and maintenance of magnetic materials national measurement standards; it is also responsible for designing industrial magnetic materials measurement equipment and related value transfer technology. In the mean time, Magnetic Materials Measuring Laboratory also acts as National Center of Quality Supervision and Inspection of Magnetic Materials, which is...

  • Research and Development of Online Magnetic Measurement...

    The project aims to determining magnetic properties of electrical steel in production line. The quality of electrical steel sheets is to a large extent dependent on their magnetic properties. Epstein and single sheet tester method could not...

  • Enterprise Energy Management System(EMS)

    An EMS system based on B/S mode and a real-time database platform was developed. Besides, a set of energy information collection, monitoring and management plat form was established successfully....

International Cooperation

  • From 2005, Magnetic Materials Measuring Laboratory has been cooperating with Hirst Magnetics Instruments Ltd, UK, on a new hard magnetic material instrument, Pulsed Field Magnetometer.

  • From 2004, being a member of IEC TC68, Magnetic Materials Measuring Laboratory has attended IEC TC68 meeting every year.

  • From 2008 to 2010 Magnetic Materials Measuring Laboratory took part in the inter-comparison exercise on measurement of magnetic moment with Vibrating Sample Magnetometer, which was held by the IEC TC68 Working Group 2.

  • In 2010, in cooperationwith National Physical Laboratory, Magnetic Materials Measuring Laboratory finished the Comparison of Permanent Magnet Measurements Report on measurement using methods compliant with IEC 60404 part 5 and Pulse Field...
