Abstrakt v dalším jazyce:	Two approximate formulae for skin effect in conductor of rectangular cross section were derived in the last time. They differ in the current distribution not only in the conductor volume but also on its surface. Since the current distribution in the conductor cannot be measured, we are limited to the measurement of effects on conductor surface and its environment. The potential drop was measured on the surface, but its sensitivity and precision is too low. Therefore flux density of magnetic field generated by current in the conductor was calculated for skin effect and uniform distribution. Then the magnetic field was measured. Unfortunately, at frequency of 1200 Hz where the skin effect was evident the exciting current was to low, to find good agreement with theoretical prediction. However it ii only technical limitation, that will be eliminated in the future.
