Procedure
- From the loops very little can
be known about
the actual magnetic field lines.
- The idea is to
manually draw
the loops on a
computer screen and comparing these curves with
the shape of field lines with a range of different
alphas.
- The best fitting
field line, for a given loop, would
give the best estimate of α for that
particular loop.
