Abstract: The present application discloses a magnetic block, which comprises a block body, a hollow magnet and a fixing device; wherein each surface of the block body has a hole having a same depth and size as the hollow magnet defined thereon; and the hollow magnet is fixedly mounted in the hole defined in the block body via the fixing device. By defining the hole having a same depth and size as the hollow magnet and fixedly mounting the hollow magnet into the hole defined in the block body, each surface of the block body is even, and it is convenient to replace the magnet. The present application further discloses a manufacturing method for the magnetic block, and structures of magnetic magic cubes created by a magnetic column and the magnetic blocks formed by the manufacturing method are in many different formations.
