Magnetism is a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnets and can be magnetized themselves, commonly iron, nickel, and cobalt. Magnetism arises fundamentally from two sources: the electric currents generated by the movement of electrons in atoms, and the spin properties of these electrons. The field of magnetism encompasses a range of magnetic behaviors, including paramagnetism, diamagnetism, and antiferromagnetism, each depending on how the material’s electrons interact. This property is not only crucial in everyday applications, such as electric motors, transformers, and storage media like hard drives but also forms the basis of various medical technologies, including MRI scanners. Magnetic phenomena are also essential in scientific research, providing key insights into the structure of matter at the atomic and molecular levels.
