Watch on YouTubeVideoPoles of a magnet
Every magnet has two poles — called North (N) and South (S). That's where its magnetic power is strongest.
If you dip a magnet in iron filings, they cling mostly at the ends (poles), sparsely at the middle.
Basic law:
- Like poles REPEL (N↔N, S↔S push apart)
- Unlike poles ATTRACT (N↔S pull together)
If you break a magnet in half, you get TWO smaller magnets — each with its own N and S. You can never isolate a single pole.
Example
Bring two bar magnets end-to-end. If they push apart → same poles facing. Flip one → they snap together.
💡 Tip:You can test an unknown metal rod: if its middle attracts a magnet less than its ends, it's already a magnet.
