'''Electromagnetism''' is one of the four [[fundamental]] [[interactions]] of [[nature]], along with [http://en.wikipedia.org/wiki/Strong_interaction strong interaction], [http://en.wikipedia.org/wiki/Weak_interaction weak interaction] and [[gravitation]]. It is the [[force]] that [[causes]] the [[interaction]] between [[electrically]] charged [[particles]]; the areas in which this happens are called electromagnetic [http://en.wikipedia.org/wiki/Field_(physics) fields].

''Electromagnetism'' is the [[force]] [[responsible]] for [[practically]] all the [[phenomena]] encountered in daily life (with the exception of [[gravity]]). [[Ordinary]] [[matter]] takes its [[form]] as a result of intermolecular [[forces]] between [[individual]] [[molecules]] in matter. Electromagnetism is also the [[force]] which holds [[electrons]] and [http://en.wikipedia.org/wiki/Protons protons] together inside [[atoms]], which are the building blocks of [[molecules]]. This governs the [[process]]es involved in [[chemistry]], which arise from [[interactions]] between the [[electrons]] orbiting [[atoms]]. However, electromagnetic [[force]] does not [[create]] the "pushing" or "pulling" between two separate material objects (lifting up a coffee cup, for example); see the [http://en.wikipedia.org/wiki/Pauli_exclusion_principle Pauli exclusion principle].

The [[force]] of ''electromagnetism'' is [[manifested]] both in [http://en.wikipedia.org/wiki/Electric_field electric fields] and [http://en.wikipedia.org/wiki/Magnetic_field magnetic fields]; both are simply [[different]] aspects of electromagnetism, and hence are [[intrinsically]] related to each other. Thus, a changing electric field generates a magnetic field; conversely a changing magnetic field generates an electric field. This effect is called [http://en.wikipedia.org/wiki/Faraday%27s_law_of_induction electromagnetic induction], and is the basis of operation for [http://en.wikipedia.org/wiki/Electrical_generator electrical generators], [http://en.wikipedia.org/wiki/Induction_motor induction motors], and [http://en.wikipedia.org/wiki/Transformer transformers]. [[Mathematically]] speaking, magnetic fields and electric fields are convertible with [[relative]] [[motion]] as a [http://en.wikipedia.org/wiki/Four_vector four vector].

[http://en.wikipedia.org/wiki/Electric_field Electric fields] are the [[cause]] of several common [[phenomena]], such as electric [[potential]] (such as the voltage of a battery) and [http://en.wikipedia.org/wiki/Electric_current electric current] (such as the [[flow]] of [[electricity]] through a flashlight). Magnetic fields are the [[cause]] of the [[force]] [[associated]] with magnets.

The electromagnetic force operates via the exchange of [http://en.wikipedia.org/wiki/Messenger_particle messenger particles] called [http://en.wikipedia.org/wiki/Photon photons] and [http://en.wikipedia.org/wiki/Virtual_photons virtual photons]. The exchange of messenger particles between bodies [[acts]] to [[create]] the [[perceptual]] [[force]] whereby instead of just pushing or pulling [[particles]] apart, the exchange [[changes]] the [[character]] of the [[particles]] that swap them.
