PROBLEM TO BE SOLVED: To provide educational tools having a magnet by which rotation is continuously performed, appealing power of fun of the magnet is increased and whose margin for demonstrating imagination is large, while being simple in structure. SOLUTION: The educational tool is provided with a plurality of blocks each of which supports a rotor, having the magnet to a support base in a freely rotatable manner, and a motor which performs rotation drive of a rotor of a first block which is one of the blocks; the blocks are arranged by optionally changing distance between the blocks, direction of rotors of the blocks or/and height positions of the blocks and presence/no presence of non-contact rotation and the rotational direction of rotors of other blocks are adjusted by rotation of the rotor of the first block by the motor.
