    The direction of the magnetic field depends on the direction in which the current flows. Apply some current to a coil and it will have a magnetic field that you can detect. If it is in the "wrong" direction, reverse the direction of current flow.

    you are right. i tested that. but i will use a PLC or Micrcontroller to control the direction that why i need the circuit.
