Abstract
The magnetic leakage fields are investigated experimentally on rectangular-slit aw models for various magnetizing fields H 0. It is shown that in certain cases the aw parameters can be incorrectly classified as a result of coincidence of their leakage fields. This is associated with both the choice of the magnetizing fields H 0 and the effect of the aw width on the dependence of the aw field on H 0: for wide aws this dependence is close to a linear function, whereas for narrow aws the dependence tends to the magnetization curve of the sample.
