Ok, thanks. So the current "flows" along the cylindrical shell? I.e inside the shell we don't enclose any current.

Hi. In this task we're asked to calculate the magnetic field inside the small cylinder (0>r>r1). The answer is zero, which I don't quite understand...Here is the picture: http://bildr.no/image/WTJ1VG5F.jpeg As the picture shows there's a current I going through the inner cylinder. Wouldn't this...

Thanks! sorry for the late response, but.. why is the magnetic field generated by the loop current nulled out?

Thanks, but when in the video does he say that? I can't seem to find it.

Hi. In this video: he ignores the magnetic field from current 2(I2). Could anyone give me a good explanation why?
