Electromagnetism is a fundamental force in nature that combines electricity and magnetism.Electromagnetism is based on the interaction of electric charges and magnetic fields.Moving electric charges create magnetic fields, and changing magnetic fields induce electric currents.Electric Charge: Fundamental property of particles that can be positive or negative.Electric Field: A region around an electric charge where it exerts a force on other charged objects.Magnetic Field: A region around a magnet or moving charge where it exerts a magnetic force on other magnets or moving charges.Creating Electromagnets:-An electromagnet is a temporary magnet that can be turned on and off by controlling the electric current flowing through it. It consists of a coil of wire wrapped around an iron or steel core. When current flows through the coil, it creates a magnetic field, making the iron core magnetic.
