Answer:

The magnetic compass shows no deflection.

Step-by-step explanation:

  • When a magnetic compass is placed on a current-carrying conductor, the compass needle shows deflection.
  • When the direction of the current is reversed, the needle deflects in the opposite direction.
  • This is due to the fact that the current-carrying conductor generates a magnetic field around it.
  • If the direction of the current is reversed, the magnetic polarization changes.
  • This phenomenon was first noticed by Oersted, and later it helped to develop electromagnetism.
