Methods of Measuring Strong Magnetic Fields

Descriptions which are briefly theoretical and essentially practical are given of a number of the techniques of magnetic field measurement, used or developed in the period of about twenty years since the last review of the subject. Particular attention is given to the application of the phenomenon of magnetic resonance while other subjects discussed are magneto-resistance, Hall effect, peaking strips, the generator principle and various fluxmeters. The uses which are made of the force exerted on a current-carrying conductor in a magnetic field are given though some of these are not, strictly speaking, field measurements. The measurement of the position of the magnetic median plane of a magnet is discussed. The last paragraphs are devoted to a description of a few methods which do not find very wide application. A list of about 150 references is appended. These are classified in groups under the heading of each particular method.
