From the magnetic induction of current, we can know that current can generate a magnetic field, and the magnetic field has energy (magnetic field energy), and the magnetic field has a force on the current.
In a closed conductor, this electromotive force can generate a current. This phenomenon is called electromagnetic induction. The induced electromotive force can be generated by the following methods:
Make the conductor cut the movement of the magnetic field in a strong magnetic field, or make the magnetic field cut the conductor, such as a DC generator.
Move the magnetic field around a conductor, such as an alternator.
An alternating magnetic field passes through the coil to generate an induced electromotive force, such as in a static device such as a transformer.
