Have you ever tried pushing two magnets together and felt an invisible cushion pushing your hands apart?
Every magnet has two special ends called poles, labeled the north pole (N) and the south pole (S), where the magnetic force is strongest.
📊A clean, bright diagram of a standard rectangular bar magnet. The left half is bright red labeled 'N' for North pole, and the right half is bright blue labeled 'S' for South pole. Sparkle/force icons highlight both ends to show that the magnetic force is strongest at the poles. Labels indicate 'North Pole' and 'South Pole' clearly in #1e2945 text with light rounded card containers.
What happens when you bring different pairs of poles near each other?
Opposite Poles Attract, Like Poles Repel
When you place opposite poles near each other (North and South), they pull together in a force called attraction.
When you put matching poles together (North facing North, or South facing South), they push each other away in a force called repulsion.
📊An interactive or animated comparison card showing three magnet pairing scenarios side by side or stacked: 1) 'Opposites Attract': Red N facing Blue S with bright green arrows pointing toward each other (Pulling together!). 2) 'Likes Repel': Red N facing Red N with orange arrows pushing away from each other (Pushing apart!). 3) 'Likes Repel': Blue S facing Blue S with orange arrows pushing away. Clear badges say 'ATTRACT (PULL)' and 'REPEL (PUSH)'. Responsive layout fitting within 350px width cleanly.
In 1600, scientist William Gilbert discovered this push-and-pull behavior while studying why navigation compasses always point North.
A common mistake is thinking magnets only pull things in. While a magnet will pull ordinary iron nails, two magnets can push each other away with great force!
Super-fast Maglev trains use this exact repelling push force to float several inches above the track, letting them glide forward with zero friction from wheels.
Key takeaways
- Opposite (unlike) magnetic poles attract: when a North pole and a South pole face each other (N−S or S−N), they exert a pulling force toward each other.
