## Caption

A magnetic field is the region around a magnet or moving charge where magnetic forces act. We visualize it using field lines: arrows show direction, spacing shows strength.

How we make the invisible visible:
	•	Iron filings align along the field’s shape.
	•	Viewing film reveals poles with shifting light patterns.
	•	Ferrofluid dances in 3D, tracing field contours.
	•	Digital sensors map the field in space and time.

Those loops you see leaving the north pole and curving into the south? That’s the geometry of magnetism itself — elegant, ordered, and crucial for everything from MRI scanners to electric motors.

👉 What’s your favorite way to see a magnetic field?
