The Law of Magnetic Induction
The Law of Magnetic Induction states that a changing magnetic environment creates an electric current in a nearby conductor. When magnetic flux through a coil of wire varies—either by moving a magnet near it or changing the magnetic field strength—it induces a voltage (electromotive force). This principle underpins many electrical devices, such as generators and transformers. Essentially, it shows that electricity can be generated by altering magnetic conditions around a conductor, linking magnetism and electricity in a dynamic, cause-and-effect relationship.
