摘要：Apparatus for measuring the internal field intensity H of a magnetic bodyhaving opposite poles surfaces includes an elongated magnetic potential measuring coil,one end of which is placed in contact with one of the pole surfaces of the body beingmeasured, while the body is subjected to a magnetic field of variable intensity generatedby an iron- free coil having lines of force passing through the body in directionsperpendicular to the pole surfaces of the body being measured, the other end of themeasuring coil being placed at a location which is uninfluenced by the magnetic potentialat either of the poles of the body in one example and, in another example, being placedin contact with the other pole surface of the body. Values for B may also be measured bya second coil at the same time.
