Self Assessment Quiz

1. Calculate the magnetic scalar potential at a distance z from a circular current loop of radius a and hence calculate the magnetic field at that point.

2. A current sheet of    (in kA/m) separates two regions of space at z=0. The magnetic field   in region 1 (z>0) is given by  (in mT) exists. If both regions are non-magnetic, determine the field in region 2 (z<0).
