In my textbook, it uses a sack shape surface to explain why Ampere's law didn't work for a changing electric field between a capacitor. Why did they use this sack shape? Why not just use the same circle around the empty space between the capacitor, where its surface is normal to the electric flux, and calculate using the circumference?
This is sort of what it looks like http://teacher.nsrl.rochester.edu/phy122/Lecture_Notes/Chapter35/chapter35.html
But in my book, the sack shape isn't a perfect cylinder, so the magnetic field does not look like it would be uniform over the whole surface.
Thanks
