Problem Two long parallel wires carry currents of I 1 =3 A and I 2 =5 A and are separated by a distance d =20 cm as shown in the figure. Find the magnitude and direc.on of the B field at: a) a point midway b) at the point P shown in the figure 22. 33 Magne&c Force Between Two Parallel Conductors § The force on wire 1 is due to the current in wire 1 and the magne.c field produced by wire 2. § The force per unit length is: 22. 34 § Parallel conductors carrying currents in the same direc.on [email protected] each other. § Parallel conductors carrying currents in the opposite direc.ons repel each other.

A. B. C. D. Quiz Two parallel wires A and B carry 0.3 A and -0.6 A currents (opposite direc.ons), respec.vely. § How does the force per unit length that A exerts on B compares (F AB ) to the one that B exerts on A (F BA )? 22. 35 ! F AB L = ! F BA L Current in wire B is reversed and current flows in same direc.on in both wires. § How does the force per unit length that A exerts on B compares (F AB ) to the one that B exerts on A (F BA )?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
