Physics Help Forum Maxwell's equations

Faraday's induction equation is only one of the Maxwell equations so is not the whole story.

You will find this link to be informative.

Thank you for your comments that support my theory.

If you are saying that $\displaystyle \nabla \times E = -\frac{\partial B}{\partial t}$ is incorrect then, no, I do not agree with you. I was saying that Faraday's equation is part of the four Maxwell equations and all of them are necessary to describe EM fields. It may be of interest that Hecht is able to derive the Maxwell equations in a non-standard way (I think it is anyway) but I very much doubt he invalidated any of them.

You have consistently ignored any request to explain how you are using the word "luminous" to describe an equation.
