A current i=−40mA is flowing through the two infinitely long straight wire segments connected by a semi-circular arc, as depicted in the figure. The semi-circular arc has a radius R=18mm . Point A is equidistant from both the infinitely long straight wire segments and also very far away from the semi-circular arc. The coordinate directions are shown in the figure. Note: If the value of current given in the question is positive, then direction of current flow will be the same as depicted in the figure. For the negative value of current, the direction of current flow will be opposite to the direction shown in the figure. a) Find the magnetic field in unit vector notation at point A. (x,yx,z component
Solve d) only

a) Find the magnetic field in unit vector notation at point A. (x,yx,z component)
Use fig-2 image for answering b)
b) Find the magnitude of magnetic field at point B.
c) From Fig.2, find the magnitude of magnetic field at point C, which is very far away from point B .
d) from fig 2 : Let the distance between point C and B becomes zero, then calculate dipole moment and draw the figure.
