The electromagnetic field is a physical influence (a field) that permeates through all of space and which arises from electrically charged objects and describes one of the four fundamental forces of nature - electromagnetism. It can be viewed as the combination of an electric field and a magnetic field. The electric field is produced by non-moving charges and the magnetic field by moving charges (currents); these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell's equations and the Lorentz Force Law.
Nature of the electromagnetic field
As with many physical concepts, there are various ways of thinking about the electromagnetic field. The field may be viewed in two distinct ways.

@elicachung Everyone has an electromagnetic field; an energy field around them that can be measured and seen.

@docfreeride Well, technically if they were gas and I were to supercharge them within the confines of an electromagnetic field they'd work.
