An intrinsic joint resistance can arise due to circulating Hall curren
ts flowing across the Joint interface between dissimilar metal conduct
ors carrying transport current in a magnetic field. Calculations have
been performed to determine this resistance for a number of generic jo
int geometries, including butt, sandwich, and lap, as a function of th
e magnetic field strength for Cu-Al and Cu-SC pairs. This type of join
t resistance may play a role in the coupling loss and stability of fil
amentary superconductors. The results are discussed in terms of their
implication for superconducting coil and conductor design.
