Engineering Physics Annotation << Back RESONANCE PHENOMENA IN MAGNETIC MATERIALS V.A. SANDOVSKII The experimentals results in dependence of permeability from frequency at measurement upon specimens surface at local area. The method for permeability measuring at alternate fields is given. It founded upon theoretical calculation as well as experimental data. There is showed, that in the range 20…100 kHz resonance phenomena can be seen with a great evidence and correspondent curves essentially changes in dependence with a specimens materials. Some experimental curves as found to be contained a frequency hysteresis loops. Experimental gear is showed as well as resulting graphics. As a most important result is the method can be recommended for magnetic materials testing. Key words: permeability, frequency, alternated field, hysteresis loop, diagnostic, resonance.
