Question

An infinitely long thin metal strip of width w=12cm carries a current of I=10A that is uniformly distributed across its cross section. What is the magnetic field at point P a distance a=3cm above the center of the strip as shown? This one requires some integration! I suggest you solve it symbolically first, then plug in numbers.

So what is your question? This is an integration problem. Draw the figure, and do the integration. Use symettry.
