P1. (6) An infinitely long wire carrying current I passes just under a circular loop of radius a, also carrying the same current I as shown in the Figure. (a) Find the magnitude and direction of the B field at points P1 and P2. Note that d >> a. (hint: using magnetic dipole approximation) (b) What is the mutual inductance between the wire and the loop?
