How do I represent the properties of magnets using magnetic field lines?
In this post, we use magnetic field lines to model qualitatively the direction and strength of magnetic fields produced by magnets, current-carrying wires and solenoids and relate these fields to their effect on magnetic materials that are placed within them, as a part of the Preliminary Physics course under the module Electricity and Magnetism and sub-part Magnetism.
The following video covers how you can use magnetic field lines to model the magnetic field around a solenoid and wire.
