Class 12 Magnetism Notes Introduction to Magnetism: Magnetism is a fundamental force in nature that manifests itself through the behavior of magnets and magnetic fields. It plays a crucial role in various aspects of physics, engineering, and technology. Magnetic Fields: A magnetic field is a region around a magnet or a current-carrying conductor in which a magnetic force can be experienced by another magnetic pole or a moving charge. Magnetic fields are represented by magnetic field...
