An observation of variable magnetic forces depending on adjacent surface shapes of bordering magnetized materials

In this paper, it is newly presented and discussed that when two magnetized materials are sufficiently close, total force of magnetic materials can be variable by depending on the adjacent surface shapes. This means that when two magnetized bodies are adjacent or in contact, the total force is not uniquely defined and depends on the bordering surface shapes even though the total volume is maintained as a same level. It shows that the range of variable force falls into even repulsion to attraction.
