This model made by Anthony Sefa on COMSOL Multiphysics 6.2 is a 2-dimensional demonstration that simulates a bar magnetic relative to its magnetic field. To study the magnitude of the field in Tesla (T) Anthony preformed a stationary study of two 1D plot groups. In the first group labeled Magnetic Field Along the Air Domain (vertical) he studied the strength that the magnet has as you cross over it going from the top to the bottom without passing through the magnet. The second plot group labeled Magnetic Field Along the Air Domain (horizontal) shows the strength of the magnet horizontally which demonstrates the pulling and pushing factor of the magnetic field. You can visually see the electromagnetic field lines moving by toggling with the (local time) slide under the tab labeled (Streamline) which is under the setting (Magnetic Flux Density Norm (mf)).
