| titleOfInvention | A high resolution magnetometer |
| abstract | A particle sample (6) to be measured is placed in the alternating field of one of a pair of special transducers (1 and 2). Each transducer is comprised in part of a high permeability magnetic body (5), shaped to have a central limb, around which is positioned an excitation coil (4), and an outer return limb. The rest of the magnetic path consists of an air gap in which a detector coil (3) is positioned to be co-axial with the excitation coil. The outputs of the pair of transducers is compared. The extra emf induced by the sample appears as a difference signal which is amplified by an amplifier (7). After further amplification stages the signal is passed through a phase sensitive detector and an indication of the number of particles in the sample is displayed on a display unit. Zeroing of the device, prior to introduction of the sample (6) can be achieved either by varying the position of two metal masses (8) (one ferrous, one non-ferrous), on the axis of the unit and/or by adjusting a variable resistor (9). |
