Abstract :
Magnets in free space can be modeled using the surface charge model [1]. This model assumes that a magnet can be represented as a layer of positive charges on the top surface of the magnet and a layer of negative charges on the bottom of the magnet. In case of cuboidal magnets this results in analytical field and force [2], [3] equations.
