[en] In this paper, the crossed field demagnetization effect
of the bulk type-II superconducting materials in a variety of external
magnetic field condition has been investigated both numerically
and experimentally. A melt-textured YBCO bulk sample was
magnetized along the axial direction and after that a transverse
field perpendicular to the central axis applied. The collapse of the
original trapped field was measured using a Quantum Design Physical
Property Measurement System. A numerical solver based on
critical state model is proposed to simulate the measured results. (C) 2008 IEEE.
