A wire consists of a vertical wire whose ends are connected to a circular wire. Suppose that the vertical wire has end points at r4 = -2 cos 60° î+ Rsin 60° and r=-R cos 60° î - Rsin 60° 3, with the positive current I flowing from point A to point B. On the other hand, the circular wire has a radius R centered at the origin and passes through points A, B, and C, with the position rc = Rî. If a positive current I flows along the wire, passing through the points A, B, C, and back to A, use Biot-Savart law to find the resulting magnetic field at point D, where rp = zk. Note: you must illustrate the problem, your variables, and your coordinate systems.

Question
A wire consists of a vertical wire whose ends are connected to a circular wire. Suppose that the vertical wire has end points at rд = −2 cos 60° î+ Rsin 60° ĵ and rß = −R cos 60° î - R sin 60° ĵ, with the positive current I flowing from point A to point B. On the other hand, the circular wire has a radius R centered at the origin and passes through points A, B, and C, with the position rc = Rî. If a positive current I flows along the wire, passing through the points A, B, C, and back to A, use Biot-Savart law to find the resulting magnetic field at point D, where rp = zk. Note: you must illustrate the problem, your variables, and your coordinate systems.
