ABSTRACT:
The present invention concerns devices with probes for measuring magnetic potentials. Potential differences between two points of a material in a magnetic field are measured with a plurality of Hall probes arranged on a curved line which connects the points. The voltage of each Hall probe is connected with the summation point of an operational amplifier whose output voltage is proportional to the potential difference P=.intg.H.multidot.ds. A similar arrangement may also be used to measure the current in a conductor.
