The invention discloses a bearing inner ring wire clamping prevention cutting method based on magnetic field force, and relates to the technical field of bearing ring cutting. The problems that when an existing bearing inner ring is cut and sampled, a saw disc is prone to being broken and efficiency is low due to the fact that a traditional notch cutting mode of a cutting machine is used, and molybdenum wires are prone to being broken due to wire clamping when a wire cutting machine is directly used are solved. The bearing inner ring wire clamping prevention cutting method based on the magnetic field force comprises the following steps that axial magnetization is conducted, specifically, the bearing inner ring is placed above a magnet in a standing mode, the end face of the bearing inner ring makes direct contact with the magnet, and the bearing inner ring is taken down after the contact time reaches the set time; and linear cutting: cutting the magnetized bearing inner ring by using a linear cutting machine,
