Magnetization device

A magnetization device is configured for magnetizing a magnet. The magnetization device includes an annular base, tooth structures, shoe structures and coils. The annular base has a hollow structure. Each tooth structure has a first end and a second end, and the first end of each tooth structure is connected to the inner edge of the annular base. The shoe structures are respectively connected to the second end of the tooth structures, and the shoe structures are arranged relative to each other to form a holding space for placing the magnet. Each coil is wound on the corresponding one of the tooth structures, in which the winding directions of the coils corresponding to any two adjacent tooth structures are opposite.
