ABSTRACT:
We report on the progress on computing the current maps from 
the magnetic induction in bulk samples of YBCO melt-textured
compounds. Typical sample size is in the cm range and 
induction maps are obtained by Hall probe measurements.
Currents are obtained by solving the inverse Biot-Savart
problem. No assumption is required on the number of domains
or geometry of the sample; the only constraint in the model
is that the current circulation should be confined in the
basal plane and uniform in the sample thickness.
