Segment BC is an are of a circle with radius 30.0 cm, and point P is at the center of curvature of the arc Segment DA is an arc of a circle with radius 20.0 cm, and point P is at its center of curvature. Segments CD and AB are straight lines of length 10.0 cm each. Calculate the magnitude of the magnetic field at a point P due to a current 11.4 A in the wire. Express your answer with the appropriate units. What is the direction of magnetic field? into the page out of the page
