Agilent / HP 16454A

This Magnetic Material 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 Agilent 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.
