A square loop of side length a=2.57cm is placed a distance b=0.81cm from a long wire carrying a current that varies with time at a constant rate as,I(t)=Qtwhere Q=7.03A/s is a constant.

A) Find an expression for the magnetic field due to the wire as a function of time at a distance r from the wire in terms of a, b, Q, t, r, and fundamental constants. B) What is the magnitude of the flux through the loop? Select the correct expression. C) If the loop has a resistance of2.04?, then what is the induced current, in amperes, that flows in the loop? D) In what direction does this current flow?
