Comparing Faraday's and Ampere's laws as modified by Maxwell, the asymmetry between them is that

  • A.Ampere's law contains no time derivative
  • B.Faraday's law applies only to stationary circuits
  • C.Ampere's law has a conduction current term with no magnetic counterpart
  • D.Faraday's law has no time derivative in it

Answer: C

Both contain a time derivative of a flux density, but only Ampere's has a source current, because no magnetic current of monopoles exists. That single asymmetry runs through the whole of the theory and is the deepest structural difference between electricity and magnetism.
