Magnetic Field And Permeability Measurement
MAGNETOMAT 1.790
Foerster Instruments, Incorporated
The MAGNETOMAT 1.790 is a measuring system for the precision detection of magnetic flux density and relative permeability. The MAGNETOMAT software is used for displaying the measured values and saving and exporting data. The wide range of probes facilitates optimal adjustment to the conditions of the application, such as the measurement of relative permeability within the scope of the quality control of stainless steel and low-permeable (non-magnetic) alloys. Further applications include the long-term monitoring of the magnetic environment, e.g. prior to installing magnetically sensitive devices, and the localization of ferrite enclosures in stainless steel and NE materials. Changes in material (sulfidation, degradation of lamination, structural changes) can also be proven thanks to permeability comparative measurements.

Magnetic Material Test Fixture
16454A
The 16454A is designed for accurate permeability measurements of toroidal-shaped magnetic materials. Since the construction of this fixture creates one turn around the toroid (with no magnetic flux leakage), the need of winding a wire around the toroid is unnecessary. Complex permeability is calculated from the inductance with and without the toroid. When the E4991A/4291B with option 002 is used as the measurement instrument, direct readouts of complex permeability are possible. In addition, it is furnished with a small and a large fixture to adapt to a wide range of sizes.
