Abstract
Method and apparatus for detecting in a sample a substance which responds to an applied magnetic field, such as a paramagnetic substance. The sample is placed in an applied magnetic field, and the effect of the sample on a performance characteristic of an electrical conductor is correlated to the presence of the substance. The method and apparatus may be adapted for qualitative and quantitative determination.
