Abstract
The effect of a conducting permeable spherical particle on the impedance of a solenoid is calculated, and consideration given to maximising the effect for detection purposes. For greatest sensitivity either the resistive change or the reactive change should be optimised, according to the method of detection; the frequency ranges needed to do so are indicated for both magnetic and non-magnetic particles
