Abstract: High-T, superconducting pancake coils wound by Ag-sheathed Bi-based tapes have
been placed in between ring-shaped mu metal sheets. The central magnetic field Be of
a single coil was found to be enhanced by 60 % at liquid nitrogen temperature 77 K,
and increased N 26% for a four-coil stacked magnet. Critical currents of these coils were
decreased. Bs was also increased when the magnet was wrapt by a mu metal sheet. This
indicates that the well-designed high permeability materials can significantly enhance
the magnetic fields generated by high-Tc superconducting magnets.
