Electric Field from Maxwell's Equations

AI Thread Summary
To determine the electric field from Maxwell's equations, specifically using the third equation in differential form, one must apply boundary conditions relevant to the problem. The process typically involves solving the differential equations that describe the electric field in the context of the given conditions. The discussion highlights the need for specific details to provide a comprehensive answer, as the question is considered vague and open-ended. Understanding the context and parameters is crucial for accurately calculating the electric field. Overall, solving for the electric field requires a clear framework and specific information.

How would you determine the electric field from Maxwell's equations? One of my friends was asked this when he went for a Master's interview. Thanks.

This is a very vague and open ended question. What other details are given?
 
If you meant is how to calculate the electric field, then since Maxwell's equations are basically differential equations you obviously need boundary conditions.

Hi, He was given the third Maxwell equation in differential form and asked how he would find the Electric field. Sorry I can't give you much to go on.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
