Shape variations directly rewrite the rules of magnetic fields:
Edge effect: The magnetic field strength at sharp edges is 3-5 times greater than in flat areas.
Directional control: Grooved structures can guide magnetic field lines to form specific paths.
Three-dimensional focusing: Curved designs allow the magnetic field to be projected directionally like a spotlight.
These characteristics make irregularly shaped magnets excel in environments requiring localized strong magnetic fields or complex magnetic circuits.
