The principle of magnetism, which states that like poles repel and opposite poles attract, is applied to the dimensions of the U-shaped magnet. The dimensions are 95mm long, 63mm wide, and 17mm high. The weight of the magnet is 164.2 grams.

This set of magnets is used in the teaching of physics.Experimental and demonstration teaching tools for primary school science experiments and middle school physics experiments. They can also be used for student stationery, preschool toys, etc. It can not only allow students to intuitively feel the real existence and changes of the magnetic field, but also express its physical characteristics concretely, vividly, and more importantly, it can arouse students' learning interest, concentrate their attention, and stimulate their thinking and imagination. This will greatly help and promote the understanding and cognition of magnetic fields for primary and secondary school students and children. Magnetic fields are beneficial to the body, and children can also use the N and S poles of magnets to repel the same polarity as the Earth's magnetic field.The principle of attraction between the opposite sex
