🧲 Magnet & Paperclips — Invisible Force

Watch paperclips jump to a magnet! Drag the magnet around and see the invisible magnetic force in action. Perfect for ages 5–8.

Magic Around Us3DEasy60 FPS⚡ Plasma

Drag the magnet around and watch paperclips fly through the air to stick to it! This simulation shows how the invisible magnetic force works — even through empty space.

🔬 What It Demonstrates

Magnets create an invisible magnetic field — a region of force that affects iron objects. The field is strongest near the poles (N and S ends) and weakens quickly with distance. Enable "Show Field Lines" to see the invisible field made visible!

🎮 How to Use

Drag the magnet around the screen — paperclips will be attracted to it. Click elsewhere to add more clips. Use the Strength slider to make the pull stronger or weaker. Toggle field lines to see the invisible magnetic field pattern.

💡 Did You Know?

Earth itself is a giant magnet! Its core contains liquid iron that creates a magnetic field around the entire planet. This is what makes compass needles always point north — they align with Earth's magnetic field lines, just like the paperclips in this simulation!

⚙ Under the hood

Drag the magnet and watch paperclips fly to it! See magnetic field lines and discover how the invisible force works.
