Analysis and Calculation of The Magnetic Moment of a Magnet Compensation for Type “A” Magnetic Needle

Abstract

Our aim is to renew the compensation system, which is been used until now, and was depending of the compensation magnets got from the market. These magnets have a relative power noted by the manufacturer and we have to calculate how many correctors we go to use as well as where to place them according to the deviations we obtain from balanced ship. With this paper, we show a new system to calculate the place of the compensation magnets but in reference to the magnetic moment of four compensation magnets, which will be placed in a plate and then turned appropriately in order to generate a complex magnetic field, which is been used to compensate the deviations of the magnetic compass.
Having this idea in mind, by different experiments and measurements, we have calculated the magnetic moment of one compensation magnet, and thereinafter inserted in a complex formula to calculate the combined magnetic field generated by four magnets.
