A long straight wire carries a current 20 A. A rectangular loopwith two sides parallel to the straight wire has sides 2.5 cm and10 cm, with its near side a distance 1 cm from the straight wire.Find the magnetic flux through the rectangular loop. Thepermeability of free space is 4 p à 10^-7 T · m/A.
Answer in units of Wb.
The answer I got wrong on the problem was from the followingwork:
B=(4*pi*10^-7)*20/(2*pi*1) and thenFlux_m=B(3.5*Area-1*area)[meters] I got 1.98*10^-7, what's wrong,and what's the right answer?
