.~ Current through test material forms test magnetic field
DEFINITION
Classification: 324/263
Current through test material forms test magnetic field:
(under subclass 200) Subject matter which includes an electric circuit including terminals to contact a material to be magnetically tested so that current through the material and the terminals create a magnetic field in the material for test purposes.
(1) Note. Demagnetization as well as magnetization can be claimed as long as the test material forms the test field.
