#astatic_coils__astaticcoil  an arrangement of coils used in sensitive electrical instruments; the coils are arranged to give zero resultant external magnetic field when a current passes through them and to have zero electromotive force induced in them by an external magnetic field
  supertype:  #coil  reactor consisting of a spiral of insulated wire that introduces inductance into a circuit
  part of:  #astatic_galvanometer__astaticgalvanometer  has a moving magnet and astatic coils arranged to cancel the effect of the Earth's magnetic field
