field lines
Magnetic flow visualization
Field lines are imaginary curves used to visualize force fields in physics—magnetic fields, electric fields, gravitational fields.
The lines show the direction a force would act on a particle at any point, with their density indicating field strength.
The field lines around a bar magnet curve from north pole to south pole.
Though purely a visualization tool, field lines help make invisible forces intuitive.
