Magnetic fields can be created by charges or the flow of current.
An arrangement of electric charges or a current can create electric fields, magnetic fields, and electromagnetic fields. These fields are fundamental in understanding and explaining the behavior of electricity and magnetism in various phenomena and devices.
An electromagnet is created by an electric current. When electric current flows through a coil of wire, it generates a magnetic field. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the coil.
Light is generated when an atom's electrons transition to a lower energy level and release photons. This process is different from the movement of electric charges, as it involves the emission of electromagnetic radiation due to changes in electron energy states, rather than the flow of charges.
An insulator is a material that does not allow electric current to flow through it easily, while a conductor is a material that allows electric current to flow through it easily. Insulators have high resistance to electric current, while conductors have low resistance. This property is determined by the arrangement of electrons in the atoms of the material.

A Y current is the electric current through one branch of the star arrangement of a three-phase circuit.

An electromagnet is created by an electric current. When electric current flows through a coil of wire, it generates a magnetic field. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the coil.
A magnet created when electric current flows through a coil of wire is called an electromagnet.

Many - but not all - are poor conductors of electric current.
An electric current can be created by moving a magnet through a metal coil.
An electromagnet is created by running electric current through a coiled conductive wire.
Alessandro Volta created the first electric battery, known as the voltaic pile, in 1800 by stacking alternating discs of copper and zinc separated by layers of cardboard soaked in saltwater. This arrangement of different metals and an electrolyte produced a flow of electric current. Volta's invention marked a significant advancement in the development of electric power sources.
