General Description

The LDA-3A AF Demagnetizer serves for demagnetizing tumbling or static specimen by alternating magnetic field.
The demagnetization process is microprocessor-controlled and automated. One only sets up the demagnetization parameters, fixes the specimen into the specimen holder, and inserts the holder into the demagnetization coil. The rest of the demagnetizing process is performed automatically following the pre-set parameters.
Triple mu-metal shielding provides an effecive protection of the specimen from the Earth's magnetic field. The electrical current for producing the demagnetizing alternating field is derived from the electrical net current, filtered in such a way that all the higher harmonic components that may produce parasitic magnetizations are effectively attenuated.
