The two wires shown in the Figure are separated lav d=21.'~?cm and 11 I if: carry.r currents of |1=5.?9A and l2=4.29A in opposite directions. Find the net magnitude of the magnetic eld at the point P [unit {I ._ d _.. in pT. 1pT=1o6Ti Question 2 As shown in the Figure. a long. straight wire carries a current of l1=15.ol. A circular loop of wire lies below the straight wire with a distance d=D.44m form its center P to the straight wire. The loop has a radius of R = 0.26m and carries a current of |2=4.14A. Assuming that the thickness of each wire is negligible. Find the magnitude of the total magnetic field at the center C of the loop {unit in uT.1uT=1U"5'Tl. Question 3 Three long. parallel conductors carry currents of |1=|2=|3=L The Figure shows an end View of the conductors. with each current coming out of the page. Conductors I1 and i2 are located the upper corner and lower corner of a square. The diagonal distance of the square is {Ea}. lConductor I3 is located at the right side of C corner [distance = all. Find the magnitude and direction of the magnetic field at points A
