https://www.britannica.com/science/electromagnetic-field
WEBelectromagnetic field, a property of space caused by the motion of an electric charge. A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.

Electromagnet - Wikipedia
https://en.m.wikipedia.org/wiki/Electromagnet
WEBAn electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil. The magnetic field disappears when the current is turned off.

WEBKey points: When electric charges move, they create magnetic fields in the space around them. Electric charges moving through a wire create electric current. Because electric currents are made up of moving charges, they create magnetic fields. An electromagnet is a coil of wires that becomes a magnet when electric current runs through it.
