Homework Statement
This is not a homework problem, I'm working through griffiths Electrodynamics on my own.
Homework Equations
when there is an emf source, since electrosatic fields integrate to zero around a loop
The Attempt at a Solution
The solution claims that since the integral of f (force per charge) around the a loop for any electrostatic field is zero, the emf is zero since that is the only field present.
However, when I thought about this problem, I reasoned that initially the charges in the wire would rapidly reorient themselves to cancel out the external field. and since the field is 0 through out the wire, and there isn't a source of emf that generates potential differences in the metal, the current is naturally zero. This is very different reasoning, and i don't think the solutions are valid. Can anyone confirm/deny please?
