The present invention relates to a dynamic three-dimensional teaching aid that allows for alphabet teaching or storytelling for infants or children in diversified manners by dynamic movement of a teaching member with teaching content when the teaching member is moved, thereby stimulating indefinite curiosity and imagination of infants and children, meeting their learning ability, arousing interest not to be bored and to appear novel despite repeated use, and letting them actively participate in and focus on learning and that has a simplified structure, is easy to manipulate, and is accurately controllable for its movement. More specifically, the dynamic three-dimensional teaching aid is configured so that a first magnet 23 is moved under a teaching board 1 by a control rod 2, and a moving block 3 coupled with a teaching member 4 is placed, which includes an attractive force element to be attracted by the first magnet 23 and a second magnet 32, on a side of the attractive force element, to exert a repulsive force to the first magnet 23 to be rotated depending on changes in the moving direction.

A manipulative device having at least two three-dimensional bodies, each including a magnet. The at least two three-dimensional bodies including at least one first three-dimensional body and at least one second three-dimensional body. The at least one first three-dimensional body is manipulated by a user relative to the at least one second three-dimensional body, whereby the surface of the at least first three-dimensional body contacts the surface of the at least second three-dimensional body, and the at least two three-dimensional bodies engage or repel each other due to magnetic force from the magnet in each three-dimensional body. Also, the at least two three-dimensional bodies disengage or release from each other due to reduction in magnetic force from the magnet in each three-dimensional body disconnecting when separating the three-dimensional bodies from each other. A sound or noise dampening material can cover the entire surface of each three-dimensional body.

A sensing device, a ball shaft for smart magic cube, and a smart magic cube are provided. By optimizing the sensing device of the smart magic cube, only two circuit boards are needed to sense rotation states in six directions, thereby changing a current technology that requires setting PCB boards and sensors in each direction of the smart magic cube. The smart magic cube has a simple structure and is easy to assemble, which may reduce production costs.
