1.Magnets have magnetism and can attract iron - made objects.
2.Like poles repel and opposite poles attract. When two magnets approach each other, the same magnetic poles will repel and push each other away, while the different magnetic poles will attract and stick to each other.
3.Magnets have magnetic poles. Each magnet has two magnetic poles, the N - pole and the S - pole, which exist in pairs.
4.When a ferromagnetic material is magnetized, if it easily loses its magnetism, it is called a temporary magnet; when a ferromagnetic material is magnetized and does not easily lose its magnetism, it is called a permanent magnet.
