I was thinking that too. The work done by the induced electric field is positive when the proton is moved counterclockwise because the displacement is in the same direction as the electric field line. If the proton was moved clockwise, then the work would be negative, not zero, since the...

I have drawn a picture of what the induced electric field will look like, and I have determined its magnitude both within and outside of the magnetic field. I was able to get the right answer for part (b) with this information, but I don't understand why the answer for part (c) is 0 J. It...
