Abstract
The distribution of magnetic induction vector B in HTSC ceramics Y-Ba- Cu-O in rotating external magnetic field has been studied both theoret ically and experimentally using 3D neutron polarization analysis. It w as demonstrated that the vector B changes both in value and direction. Transverse and longitudinal currents with respect to the local field direction are evaluated from the first principles using Maxwell equati ons and experimental data. Their behaviour is analysed.
