Magnetism is a fundamental force of nature that arises from the motion of electric charges. It is responsible for the attraction and repulsion between objects, such as magnets and ferromagnetic materials like iron. The Earth itself acts like a giant magnet, with a magnetic field that protects us from solar radiation. In everyday life, magnetism is utilized in various technologies, including electric motors, generators, and MRI machines. Understanding magnetism is crucial for advancements in electronics and energy production, making it a vital area of study in physics and engineering.
