Anisotropic magnets are formed in the presence of a magnetic field, which aligns the material being formed along the lines of magnetic force. After the magnetization process, the magnet is magnetized only along the magnetic axis, making it very strong. Only the poles can be reversed. Isotropic magnets, on the other hand, do not require an external magnetic field during formation. They are magnetized only once, at the end of the production process, which makes them weaker than anisotropic magnets. However, isotropic magnets can be magnetized in any direction, allowing for multipolar magnetization.
