Electric eddy field

  1. Nov 24, 2008 #1

    I'm studying Maxwell's equations at the moment. To solve Maxwell's equations one can introduce scalar- and vectorpotentials and calculate the electric and magnetic field by [tex]E=-\text{grad}\,\Phi-\frac{\partial A}{\partial t}[/tex]
    I have the following question to that: Is the contribution of the time derivative of [tex]A[/tex] in the formula for [tex]E[/tex] due to the electric eddy field that is induced by a time varying magnetic field? If not, how it is possible to calculate the electric eddy field when a time varying magnetic field is given?

    Thank you for your help!

    The term "electric eddy field" is not commonly used in English. Just saying "electric field" is enough. If you take
    [tex]\text{rot}\,E=\text{rot}[-\text{grad}\,\Phi-\frac{\partial A}{\partial t}][/tex], you get Maxwell's equation that is differential equation relating E and B.
