Identify the nature of poles X and Y of the magnets in a given figure
Draw lines around a current carrying loop what happened to the magnetic field lines due to a current carrying straight conductor when the current is reversed state the rule which gives relations of magnetic field lines and direction of current

Dear student,
As the magnetic lines moves from North pole to South pole so,
i) X is North pole and Y is south pole.
ii) X is North pole and Y is south pole

ii) current carrying loop with magnetic fields



When direction of current in a current carrying conductor is reversed , then the magnetic field lines also gets reversed.
Eg - if current is flowing in downward direction then , magnetic field lines will be in the upward direction and vice versa.

Hope this information clear your doubt.
Regards.
