II：Manufacturing process and magnetizing
① With dry process can produce isotropic & anisotropic magnets, the tool can be changed and developed easily.
② With wet process only can produce anisotropic magnets,it is complicated to change the tool and the tooling charge is high.
③ Isotropic ferrite magnets can be magnetized in any direction.
④ Anisotropic ferrite magnets are all oriented in the manufacturing direction, and can be magnetized in the direction of orientation.
