The magnets of the ever-changing Rubik's Cube are usually massive and shaped like small squares. This is because magnets play a key role in the ever-changing Rubik's Cube. They are installed inside the Rubik's Cube to fix the cubes of the Rubik's Cube and enable them to rotate and adjust their positions.

The reason why the ever-changing Rubik's Cube uses magnets is that magnetism can provide a stable adsorption force, so that the cubes of the Rubik's Cube can be closely connected together while maintaining a moderate degree of rotation. In this way, when we rotate all sides of the Rubik's cube, due to the role of magnets, the small Rubik's cubes will attract each other and remain in the right position, thus realizing the disruption and restoration of the Rubik's cube.

In addition, the magnet can also provide some resistance, which makes the Rubik's cube feel smoother and more stable when it rotates. This is very important to solve the Rubik's Cube, because it can help the solver to better control the rotation of the Rubik's Cube and improve the difficulty and challenge of solving.

It should be noted that different brands and models of ever-changing Rubik's Cube may use different types and shapes of magnets to meet different design needs and experiences. Therefore, when purchasing the ever-changing Rubik's Cube, you can choose the appropriate magnet type and shape according to your personal preferences and puzzle solving needs.
