wires A and B with currents iA=2iB both directed into the page are located at coordinates (0,2) and (0,-2) respectively. The net field at the origin due to fields A and B points A. in Quadrant I B. in the negative x-direction C. in the positive y-direction D. in the positive x-direction E. in Quadrant IV F. in the negative y-direction

Two magnetic dipoles m1 and m2 (equal in magnitude) are oriented in three different ways. Which ways produce a dipole field at large distances? Briefly explain your reasoning.

Three wires with (nonzero) current flowing perpendicular to the page are spaced equally on a line as shown below. i, i, i, The first wire experiences no force due to the other two wires when the following is true regarding the current magnitudes of iz and iz: O i2 = 3i3 O i3 = i2 O none of these O i3 = 3i2 O it is impossible for the first wire to experience no force O i3 = 2i2 O i2 = 2i3

6. Three long, straight wires are mounted on the vertices of an equilateral triangle as shown in the figure. The wires carry currents of I1 = 2.00 A, I2 = 5.000 A, and I3 = 4.50 A. Each side of the triangle has a length of 42.0 cm, and the point (C) is located half way between (I1) and (I3) along one of the sides.

5. Two long, parallel wires are separated by a| distance of 0.400 m. The currents I, and I, have the directions shown. (a) Calculate the magnitude of the force exerted by each wire on a 1.8-m length of each other. (b) Is the force attractive or repulsive? I = 5.00 A 0.400 m 2.00 A

Question 1, part (c) Three straight wires of equal length are placed parallel to each other at equal distances as shown in the image. Each wire has the same magnitude current flowing through it. The current in wire 1 is directed OUT OF THE PAGE and the current in wires 2 and 3 is directed INTO THE PAGE. What is the DIRECTION of the net force on wire 2 due to the other two wires? +y +x X) Wire 1 Wire 2 Wire 3 Select an answer and submit.
