1. The problem statement, all variables and given/known data Im reviewing for a test so im doing some practice questions. need help with this one. The questions simply states "find the magnetic field at point P for the steady current configurations shown below. Because i cannot find the exact picture on the internet i am going to attempt to describe the setup, and provide a picture of a similar setup. If you were to imagine the x and y axis, the origin is the point P where the magnetic field is desired to be known. The current carrying loop consists of a quarter circle of radius a, and another larger quarter circle radius b. Both quarter circles are in the same quadrant. The 2 circles are connected by straight edges, which lay on the axis and the current circulates clockwise. 3. The attempt at a solution I understand that the magnetic field from the straight edges on the axis will not contribute to the magnetic field at P. I understand also that the magnetic field at P generated by the quarter circle with radius a, will point out of the page, and the quarter circle with radius b will point into the page, however since the quarter circle with radius a is closer than the quarter circle with radius b, the magnitude of the magnetic field due to a is greater than that of b. Therefore, the total B field will point out of the page. Im having a hard time understanding how to apply the biot savart law to this one.
