1. A magnetic field suppression system comprising:
a first coil assembly having a first winding configured to generate a static magnetic field along a first direction through a center of the first coil assembly; and
a second winding configured to generate a time-varying magnetic field along essentially the first direction;
a second coil assembly oriented parallel to and spaced apart from the first coil assembly and having a third winding configured to generate a static magnetic field essentially along the first direction through a center of the second coil assembly; and
a fourth winding configured to generate a time-varying magnetic field essentially along the first direction.
