Method for calculating magnetic induction of cylindrical heartons from critical magnetic hard materials

At this time in the field of instrumentation technology, the creation of advanced instruments is very important. On this basis, the article considers the necessary determination of the values of the main parameter of the power characteristics of the interaction between a solenoid and a magnetic core of magnetic levitation systems - magnetic induction of the core. The ability to measure the level and density of a buoy magnetolovitsionnym level sensor in ship tanks gives this device a huge number of positive features due to a levitating body, which is a sensitive element that can be placed on various measuring chambers. The method of calculation is based on using the demagnetization curve of the hysteresis loop of the magnet material.
