 The distinction is similar as in analysis of electrical circuits where [[electrostatic]] is used.[([[http://​google.com/​books?​isbn=9780470131534|Julius Adams Stratton, Electromagnetic Theory, John Wiley & Sons, 2007, ISBN 9780470131534,​ p. 225]])] If there are no changes of charge distribution (i.e. there are no currents flowing) then the analysis is said to be electrostatic,​ to distinguish it from other cases. The distinction is similar as in analysis of electrical circuits where [[electrostatic]] is used.[([[http://​google.com/​books?​isbn=9780470131534|Julius Adams Stratton, Electromagnetic Theory, John Wiley & Sons, 2007, ISBN 9780470131534,​ p. 225]])] If there are no changes of charge distribution (i.e. there are no currents flowing) then the analysis is said to be electrostatic,​ to distinguish it from other cases.
  
-In its precise ​meaning, the name "​magnetic field" refers only to the magnetostatic field or the magnetic component of the electromagnetic field. However, in a wider sense "​magnetic field" is also used to refer to electromagnetic field. This is because electromagnetic field contains the magnetic field component in which the magnetic forces are "​observable"​ as per definition of magnetic field (see table above).+In its narrow ​meaning, the name "​magnetic field" refers only to the magnetostatic field or the magnetic component of the electromagnetic field.

 The concepts of [[near field]] and [[far field]] are introduced in analysis of electromagnetic fields. All magnetostatic effects can be treated as occurring in the near field region.[([[http://​google.com/​books?​isbn=9780387201566|Nathan Ida, Engineering Electromagnetics,​ Springer Science & Business Media, 2004, ISBN 9780387201566,​ p. 1149]])] The concepts of [[near field]] and [[far field]] are introduced in analysis of electromagnetic fields.
