Complex sentence: There are generally four types of energy competing with each other to reach equilibrium: each is derived from the exchange coupling effect, magnetic anisotropy, the magnetiostatic energy of the magnet, and the magnet's interaction with external field.
Split into simpler sentences: There are generally four types of energy competing with each other to reach an equilibrium. Each of them comes from the exchange coupling effect, magnetic anisotropy, and the magnetiostatic energy of the magnet itself and its interaction with external field.
