Abstract

The magnetic materials studied most by current international projects are based on ultrafine particles, in solid or liquid matrix. In order to design a good magnetic material based on nanoparticles, it is required to know their magnetic properties. Magnetic measurements represent a relatively difficult area of electrical engineering. In order to find the magnetic properties of nanometric magnetic powders, it is very difficult to use a traditional measurement method (e.g. using a toroidal coil). In this case, it is advisable to use compensation methods. In this paper, we present a study, based on simulation, of the compensation coil installation used to obtain the magnetisation curve of the ferrite nanometric powders of NiZn to 50 Hz. The experimental installation consists of a magnetisation circuit with two identical coils, connected in opposition, and a secondary circuit used to compensate the voltages induced in the identical probe coils, without sample. The parameters for which we obtain good secondary circuit compensation are simulated by the Electronics Workbench program – version Multisim 8.
