magnetic fields
Compass needle movers
Magnetic fields are regions of space where magnetic forces act on moving electric charges and magnetic materials.
Every magnet generates a magnetic field around it, as does any wire carrying electric current.
Earth's magnetic field shields the planet from solar radiation and makes compasses work.
In physics, field lines visualize the field's direction and strength: The magnetic field around the wire formed concentric circles.
