My lecturer ask us to think about this question.(adsbygoogle = window.adsbygoogle || []).push({});

Those loop are very closely spaced, with currentIgoing in anticlockwise direction. The stack of loop have a total length ofd. What is the magnetic field, B at the point X?

(I assume the X to be directly on top of the center of the loops.)

The attempt at a solution:

Help!! I don't even know where to start. I tried to used the Ampere's Law

[tex]\oint{B \cdot dl}=\mu_0I_{enc}[/tex]

But realised I ended up getting the results for a cylinder.
