1 Consider a semi-circular quasi-filiform conductor starting at point A and ending at point B connected to a straight quasi - filiform conductor between points B and A ( cf. Fig. 1.5 ). The structure carries a steady current I that flows counter clockwise on the circular line YA and from .B to A on the straighth like to The radius of the semi-circular conductor is R. Calculate the maquetostatic field Bat Any point? on the axis of the semi circle by means of Laplace's elementary law. [30 Points]B (P ) A I A Figure 1.5. The area of the circuit YUK, to be considered has been hashed
