We studied the distribution of magnetic field over YBCO coated conductors using Low-temperature Scanning Hall Probe Microscopy (LTSHPM). We prepared YBCO coated conductors of three filamentary types. We measure the stray field above YBCO in presence of external magnetic fields. Both shielded and trapped field were studied as a function of applied fields. The results of magnetic measurement were used to obtain the one dimensional and two dimensional current distribution using the inversion technique.
