Magnetic Effect of Current

Two long straight wires are perpendicular to the page and separated by distance d1 = 0.75 cm . Wire 1 carries 6.2 A into the page . What is the current in the wire 2 if the net magnetic field due to the two currents is zero at point P located a distance d2 = 1.50 cm from the wire 2 ?

Magnetic Flux

The figure at “click here” showing a magnetic field B and a five loops . If you put each loop in a magnetic field (without rotating it) and calculate the flux , Will any two of them have the same flux ? Rank the loops from most flux , and explain why ranked them in that order .(loops a = d are circular loops shown edge-on)` .
