The magnetic lines of force inside a bar magnet:
- Aare from north-pole to south-pole of the magnet
- Bdo not exist
- Cdepend upon the area of cross-section of the bar magnet
- Dare from south-pole to north-pole of the magnet
Solution & Step-by-step Explanation
Outside a bar magnet, magnetic field lines emerge from the North pole and enter the South pole. To form continuous closed loops, the lines must travel from the South pole to the North pole inside the magnet.
