Editing Magnetostatics (section)

===Re-introducing Faraday's law===
A common technique is to solve a series of magnetostatic problems at incremental time steps and then use these solutions to approximate the term <math> \partial \mathbf{B} / \partial t</math>. Plugging this result into [[Faraday's law of induction|Faraday's Law]] finds a value for <math> \mathbf{E}</math> (which had previously been ignored). This method is not a true solution of [[Maxwell's equations]] but can provide a good approximation for slowly changing fields.{{Citation needed|date=October 2010}}
