Reference: AQA
Lines that show the direction of the force on a small positive test charge or a small compass needle, with closer lines indicating a stronger field.
A visual model that maps the field, each line leaving a magnet's north-seeking pole and curving round to enter its south-seeking pole.
Drawn from the north pole to the south pole outside the magnet, and the closer together the lines, the stronger the field.
