Abstract
A method and apparatus are disclosed for measuring the magnetic properties of magnetic materials by generating flux lines through a balanced magnetic core and through a magnetic sample placed adjacent to the core. Increased sensitivity is accomplished through a modulation of the flux in the magnetic core which is measured and subsequently demodulated to yield an electrical signal corresponding to the magnetic properties of the material being tested.
