Are you trying to say that, it's not possible experimentally, to subject a dielectric or metal to an appreciable "induced electric field" ?

You can consider any good text on basic electrodynamics to be the reference. Yes, you mean the charge conservation equation, right? So what, the point is being same, they don't behave same. And I thought it would be easy to explain the problem. I'm supposing that you're talking about a...

I think it's safe to imagine a static case, where the change in magnetic field is very slow and monotonous, and the metal is also uniform without any symmetry problem.

What is the point here ? whatever you said is fine, though. And should result in induced charges at the surface of the metal due to pure curl electric field.

Of course, Inducing charges on the surface of a metal is totally different than inducing current inside the conductor.

Pure curl electric fields cannot induce charges in any metal, for metals would always tend to have the net electric field zero inside, and any pure curl electric field can be represented to be made of smaller loops or 'curls' using Stoke's theorem. So they always end up having eddy currents...

There are different ways to check this, for example a homemade experiment would be to put a short circuited parallel plate capacitor perpendicular to the electric filed, for electric fields produced by charges this capacitor will get charged but for induced electric field there won't be any...

No takers !? :))

I'm talking about the usual induced electric filed produced by changing magnetic flux. I don't follow what are you describing though, please elaborate.

Hi everyone, I just wanted to know/understand that, why do the dielectrics don't get polarized, when subjected to induced electric field ? Because, according to the definition of electric field(which is a vector), it is the force per unit charge, which implies, that electric field has a unique...

I was trying to explain that there is NO meaning of suddenly without specifying a reference frame. I never said anything about any spacetime event(I feel the concept of spacetime is far less unintuitive, compared to basic one-to-one treatment of things from the perspective of the different...

Happy to help! First of all you should ponder upon the idea that this light clock doesn't result in same calculated time difference, for different orientation of the light clock, that is, it is not a general case(try doing the same calculation with light clock being horizontal). So it is not a...

This is a very clear scenario you presented. Except you end up drawing a wrong conclusion, Let me try to clear your doubt. So long the ambulance itself is in the different frames which are observing the two events A & B, the ambulance will respond to the calls depending on which frame the...

I really like your view on this, for it is very natural to think this way, OK let me try to show the differences between the two views(of yours and others). Your view of the scenario is based on the absolute 'time' and variable 'speed of light', that's how you can easily explain the observation...

Dalespam, Thanks for your effort. I get the point ,that is, the system in which particle is emitting isotropically in its rest frame is different from a system in which we can go to a moving frame(w.r.t the emitting particle) in which the particle is emitting isotropically. Thanks all.
