The science of magnets involves complex and magical fields such as magnetic poles, magnetic fields, and magnetic substances. Magnetic poles, as the two ends of a magnet, have different magnetic properties and attract or repel each other, just like a pair of mysterious dancers in nature. A magnetic field is an intangible space around a magnet that carries magnetic force, ubiquitous like air, yet elusive.

Magnetic substances, on the other hand, are the fundamental units that make up magnets, and the arrangement of their internal electrons endows them with unique magnetism. These magnetic substances can form ordered structures under the action of a magnetic field, thereby exhibiting strong magnetic force. It is the interaction between these magnetic poles, magnetic fields, and magnetic materials that forms the cornerstone of magnetic science.

Through in-depth research on these scientific principles, we can not only better understand the essence and applications of magnets, but also develop more innovative magnetic materials and technologies. These new materials and technologies will play an important role in fields such as energy, transportation, and healthcare, promoting technological progress and development in human society.
