Part 4/10:
The inventor employs magnetic viewing paper—an intriguing material that visualizes magnetic fields by displaying division lines between north and south poles. When magnets are placed or glued together with like poles facing, the viewing paper reveals how these poles influence each other visually. For instance, magnets with opposite poles glued together exert repulsive forces visible through the paper, with division lines shifting off-center, illustrating the magnetic flux's complex behavior.
