Instantaneous Magnetic Monopole

Due to the existence of man-made laws, many phenomena that are not found in nature, can be manufactured with artificial method, such as instantaneous magnetic monopole. Suppose there is a long uniform rectangular-shaped magnet, along its middle cross section (the demarcation section of N-pole and S-pole) to cut it at very high speed, as the disconnected instant moment, one half of the magnet is the pure N-pole, and the other half is the pure S-pole. Similarly, other instantaneous physical phenomena such as instantaneous fractional charge may also be made with artificial method.
