Abstract

The B-H characteristics of soft magnetic materials such as mild steel are fairly linear below inductions of about 15 kG and above 22 kG but in between are very non-linear. Conventional B-H measuring equipment, such as the Rowlands Ring are limited to inductions below about 20 kG and cannot therefore be used to do measurements in the important non-linear region. The equipment described here uses a water cooled dipole magnet to provide the driving field for the sample and can be used to do measurements of about 1% accuracy up to inductions of nearly 30 kG. It can be used to do hysteresis measurements on both soft and hard magnetic materials and can also be used with Rowland Ring equipment. The equipment is automated under computer control
