Question

Two long, parallel transmission lines, d = 40.0 cm apart, carry I1 = 25.0 A and I2 = 75.0 A.

Don't do part A, only parts D-F.

2. Two long, parallel transmission lines, d = 40.0 cm apart, carry 11 = 25.0 A and 12 = 75.0 A. We are to find all locations where the net magnetic field due to the two wires is zero if these currents are in: i) the same direction and ii) the opposite direction. (a) We first consider case i). It is instructive to look at the currents along their axis. Consider the 4 points A, B, C, D on a plane perpendicular to the axis. At each of these points, draw the magnetic field vector B1 and B2 due to 11 and 12, respectively (you do not need to draw the length of the vectors to scale).

Answer 1

ABA BB AL 25A P 75A Barba Ba= maquetic field due to wire. I, Be a magnetic field due to wire Iz Do B = MIMO 21r e) the magnetic field at point A, can be zeso.

As the distance betwen is approximately 3 times A and I Point A and In the distance between - and I2 = 39, Mo I a B, Mo II - 2tr, B = 2tr Try 2th zu 3r Bau Mo 3 Il a Mo Il - since they have opposite direction it is very likely that at point A. maguete field will be zero. 6 for magnetic field to be Mhe thoa 40cm. Zero. Mo 75 Mo 25 2th 20/0.4th) one 0.4th=32 n=0.2 m 20cm
