1. A dynamic three-dimensional teaching aid, comprising:
a teaching board (1);
a control rod (2) for moving at least one first magnet (23) along a lower surface of the teaching board (1), the at least one first magnet (23) including an upward magnetic pole surface (231) and a downward magnetic pole surface having different polarities;
a moving block (3) placed on the teaching board (1) and including an attractive force element to apply an attractive force to the upward magnetic pole surface (231) of the first magnet (23) and a second magnet (32) to apply a repulsive force to the upward magnetic pole surface (231) to be able to rotate so that a repulsive force acts in a direction opposite to the moving direction of the first magnet (23); and
a teaching member (4) coupled to the moving block (3), wherein
the second magnet (32) is configured as a plate-shaped magnet that forms an angle with an upper surface of the teaching board (1) and that has a homopolar magnetic pole surface (322) having the same polarity as the upward magnetic pole surface (231) of the first magnet (23) and facing in a direction opposite to the attractive force element.
