well as the measuring system for other parameters like

power loss, permeability, etc. Figure 5.145 presents an

example of typical measured results.

As we can see, magnetostriction strongly depends on

mechanical stress. But Figure 5.145 also demonstrates

the second very important problem of the magnetome-

chanical effects—signicant changes of other magnetic

parameters under stress. More detailed description of

such effects was presented by Permiakov et al. (2003).

The magnetomechnical problems in design of mag-

netic devices are more complex if we take into account

that it is a multidimensional ...
