An overview of childrens magnetic building toys There are many primary magnets in iron with two opposite magnetic poles. When no external magnetic field acts, these primary magnets are disordered, their magnetism cancel each other, and they do not show magnetism. When the iron is close to the magnets, the original magnets are neatly arranged under the action of the magnets so that one end near the magnets has a polarity opposite to that of the magnets and attracts each other. This shows that iron can be magnetized by the magnet due to the presence of the original magnet. However, metals such as copper and aluminum do not have the original magnet structure, so they cannot be attracted by magnets. What is magnetic? In simple terms, magnetism is the magnetic force of a substance placed in a non-uniform magnetic field. In the same inhomogeneous magnetic field, the strength and magnetic strength of the material are determined by the direction and intensity of the magnetic force per unit mass of material. Because any material is magnetic, any material is subjected to magnetic forces in a non-uniform magnetic field. What really exists in the space around the magnetic pole is not a field line, but a field, which we call magnetic field . The mutual attraction of magnetic substances is performed by a magnetic field. We know that there is gravitation between materials, and it is a kind of gravitational field. The magnetic field is similar to a field that covers the space around the magnetic pole. The strength of the magnetic field can be expressed by the number of imaginary lines of magnetic force, where the magnetic field is strong and the magnetic field is weak. The number of magnetic lines passing through a unit section is called magnetic flux density. Looking forward to your inquiry this building magnetic blocks childrens magnetic building toys
