[SOLVED] Current-carrying loop

Consider the current-carrying loop shown in the figure, formed of radial lines and segments of circles whose centers are at point P. Find the magnitude and direction of B at P.

You can solve the problem quite easily with a straightforward use of Biot-Savart's law. What you have tried so far?

There are more people there, I don't think they are faster. They usually solve the whole problem for you, so that you don't have to make a single effort except for writing down the question. Here we have a different way to help you. We get you started and we go through the problem with you. It takes more time, but we believe it's a better way for you to learn physics.
