    Undergrad B-Fields: Deriving Faraday's Law & Why No Work?

    Thanks. I realized 1 was very dumb after remembering what conservative and close integral meant. Additionally, even I'm not sure what I'm asking or saying for 2

    Undergrad B-Fields: Deriving Faraday's Law & Why No Work?

    Yes, I'm trying to highlight two points of confusion. You're right I was not clear enough. I hope this helps. 1) I am asking why B-fields do no work on a point charge when the path integral of a charge on a B-field is non-zero? Did we define work as path integral only over conservative fields...

    Undergrad B-Fields: Deriving Faraday's Law & Why No Work?

    This statement has always confused me. Now my confusion is coming home to roast while we cover EMF. If we consider work mathematically as ∫f.dl and require integral to be path independent then of course the B-field does no work. However, it seems like there is a deeper meaning to B-fields do...

    Going From EMF to Faraday's Law to find E-field in my HW problem

    Wow! I have no idea how I missed that! That raises a different question though. If we have EQ 7.18 from section 7.2.2, then why in the solutions does Griffiths find phi first when EQ 7.18 only requires partial of B. Do I need to find phi?

    Apologizes, I meant to say dphi/dt is constant in time and space. Ok, I will look over that section in more detail now.

    Going From EMF to Faraday's Law to find E-field in my HW problem

    Ok, so I understand how to find dphi/dt that is integral of -d/dt(B "dot" da). In this case I find a Phi that is a constant in space in time which causes me confusion in next step. Edit: dphi/dt is constant... Grithff's then says E field same as a Mag field above center of circular current. He...
