Answer:

why does the compass needle get deflected when brought near a bar magnet a compass needle is a small bar magnet when it is brought near a bar magnet magnet magnetic is magnetic field lines interact with the that of the bar magnet Hence a compass needle shows deflection when brought near a bar magnet draw magnetic field lines around a bar magnet magnetic field lines of a bar magnet emerge from the north pole and terminate at the South Pole inside the net the field lines emerge from the South Pole and terminated the north pole as shown in the given figure list the properties of magnetic lines of force is the properties of magnetic lines of the forces are as follows the magnetic field lines emerge from the north pole to south Pol the March at the South Pole the direction of the field lines inside the magnet is from the South Pole to North Pole magnetic field lines do not intersect with each other
