The magnetizer in Cube Combination is used to speed up cube collection and setup by pulling or helping position cubes more efficiently, so you can combine them faster. In practice, players use it when drops start to slow down or when they want to keep cubes flowing into their crafting chain.

How to use it

  1. Get the magnetizer or magnet-related cube/tool in your inventory.
  2. Hold or place it as the guide you want to use for gathering cubes.
  3. Use it when nearby cube spawns or drops start spreading out, so items move into a better position for combining.
  4. Keep it active in short bursts rather than relying on it nonstop, since the effect is described as a boost rather than a permanent state.

In the game loop

The workflow shown in the guide is basically: gather cubes, speed up spawns/collection when needed, then keep combining into higher-tier items like plates and containers. The magnetizer fits into that loop as a convenience tool for reducing time spent running around for loose cubes. If you are trying to build fast, it helps most when your setup is already organized and you are repeatedly feeding materials into the same crafting path.

Practical tip

A good rule is to use it right after your cube drops begin to thin out, then switch back to normal combining once you have enough materials on hand. That keeps your pace steady without wasting the boost.

Source note

The best match I found is a beginner guide video that describes using a magnet-like boosting step during the early game and notes that the effect does not last forever.
