📖 The Invisible Force Field
You can't see a magnetic field, but it's very real — it can move objects without touching them! Every magnet creates a region of space around it where magnetic materials experience a force. The field exists whether or not there's anything there to feel it. Earth itself is a giant magnet — that's how compasses work. Birds may even navigate using Earth's magnetic field. From fridge magnets to MRI scanners, magnetism shapes our world in invisible but powerful ways.
