HOW DID THE KING CONTROL THE MOVEMENT OF THE ISLAND WITH THE MAGNET ?
- At the center of the island is a deep canyon with a giant lodestone, a naturally occurring magnet, in the middle of it.
- The King uses this lodestone to raise and drop the island and to keep it moving in relation to the Earth's own magnetic poles.
- The movement of Laputa has limits: it can't go beyond the king's own dominions, in other words, the islands that he controls at sea level. It also can't rise higher than four miles above the Earth.
- It is the job of the King's astronomers to do the actual manipulation of the lodestone at his orders.
