Comment (by eschnett):

 Yes, this is one way to specify the symmetries of the magnetic fields, as
 axial vector. tensorparity=-1 is implemented and should be supported, but
 since magnetic fields are one of the first use cases this may require some
 careful debugging. Please add some test cases to ensure this is working.

 The other way would be to treat it as antisymmetric tensor, which is also
 defined by 3 of its components. However, I believe that antisymmetric
 tensors are not yet supported by the symmetry thorns -- but that could be
 added.
