MCQ
North pole of a magnet can be identified by:
- ✓Another magnet having its poles marked as North pole and South pole.
- BAnother magnet no matter whether the poles are marked or not.
- CUsing an iron bar.
- DUsing iron filings.
North pole (South pole) can be identified only if we have another magnet having its poles marked as North pole and South pole because only then we can see the attraction and repulsion between $N-S$ (i.e. opposite) poles and $N-N$ (i.e. similar) poles, respectively.
