e field

2. A thin wire lies along the z-axis and carries a current I, defined to flow in the direction when I is positive. Nearby is a rectangular loop, 20 cm in the p dimension and 30 cm in the z direction. with the closest side being 3 cm from the wire. (Note: The wire lies in the plane of the loop, not perpendicular to it!) The magnetic flux through the loop is 3 itT m^2. What is I? Assume non-magnetic media (i.e., mu = mu 0). Note: You do not need to derive an expression for the magnetic field due to the line of current; feel free to use an expression from a textbook for this. (I guess that also counts as a hint...)

Explanation / Answer

for this question use the formula flux=?m = (
