Question

Choose the correct one:

• A. Magnetic field lines go from north pole to the south pole outside the magnet.
• B. Magnetic field lines go from south pole to the north pole outside the magnet.
• C. Magnetic field lines emerge from south pole and move away from the magnet
• D. Magnetic field lines emerge from north pole and move away from the magnet

Answer 1

The correct option is A

Magnetic field lines go from north pole to the south pole outside the magnet.

Magnetic field lines are the imaginary lines around the magnet which gives us the direction of magnetic field of the magnet.They emerge from North pole and enter at South pole of magnet.They flow from South to North inside the magnet, hence forming a closed loop.
