    Undergrad What causes the magnetic field inside a coaxial cable?

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

    Undergrad What causes the magnetic field inside a coaxial cable?

    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...

    Undergrad Magnetic interaction of wire and rectangular loop

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

    Undergrad Magnetic interaction of wire and rectangular loop

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

    Undergrad Magnetic interaction of wire and rectangular loop

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