Magnet pretreatment method and magnet

The invention relates to a pretreatment method of a magnet and the magnet. The pretreatment method of the magnet comprises the following steps: putting a magnetized magnet into a magnetizing coil; and electrifying the magnetizing coil to enable the magnetizing coil to generate a reverse magnetic field opposite to the magnetization direction of the magnet, so as to preprocess the magnet. Reverse demagnetization is carried out on the magnet through the magnetizing coil, the field intensity of the magnetic field of the magnetizing coil and the power-on time of the magnetizing coil can be accurately controlled, and the consistency of products is improved. 本申请涉及一种磁体的预处理方法及磁体。磁体的预处理方法包括：将磁化后的磁体放入充磁线圈内；以及对所述充磁线圈通电，使所述充磁线圈产生与所述磁体磁化方向相反的反向磁场，从而对所述磁体进行预处理。本申请通过充磁线圈对磁体进行反向退磁，充磁线圈的磁场的场强和充磁线圈的通电时间可进行精准的控制，提高产品的一致性。
