Analysis of the effectiveness of ironless magnetizing devices of magnetomeasuring instruments for testing magnetically hard materials

The considered indicators of effectiveness and the method for determining them, illustrated using an ellipsoidal solenoid as an example, afford a more well-founded choice of the optimal version of the magnetizing device of certain magnetomeasuring instruments. These indicators are approximate due to the adopted simplifying assumptions and the extrapolation of formulas derived for cylindrical solenoids to all other winding configurations. One of their shortcomings, however, is the impossibility of taking into account the fact of improvement of the design indicators during isogonal magnification of the geometric dimensions of the solenoid in connection with the increase of the specific heat transfer surface, which follows from Kelvin's theorem about the magnetic action of geometrically similar conductors.
