The HP/Agilent 16454A Magnetic Material Test Fixture is a specialized accessory for precise impedance measurements of magnetic materials, enabling accurate characterization of permeability and magnetic loss across a broad frequency spectrum. The fixture uses a single-turn configuration around toroidal samples, eliminating manual winding and minimizing magnetic flux leakage. Complex permeability is derived from inductance measurements taken with and without the material under test, making it ideal for material research, quality control, and advanced engineering applications.
