Question

hw help plz.

The figure below shows two long, straight wires carrying currents 1, - 1.50 A and 12 - 8.50 A into the page. The wires are separated by a distance a 1.20 m. (a) What are the magnitude and direction of the magnetic field at point A, halftway between the two wires? magnitude 2.33-6 direction atont non Your response differs significantly from the correct answer Rework your solution from the beginning and check each step carefully. HT counterclockwise from the +x axis (b) What are the magnitude and direction of the magnetic field at point B, at a distance a - 1.20 m to the right of the top wire? magnitude direction HT " counterclockwise from the +x axis

Answer 1

I_1 = 1.5 A __delta = delta.5 magnetic field due to log wire B = mu_0 I/2 pi r contourintegral At point A B_I_1 leftarrow. rightarrow B_I_2 (R.H.Rule) Vertical-bar B Vertical-bar = B_I_2 - B_I_1 = mu_0 I_2/2 pi (0.6) - mu_0 I_1/2 pi (0.6) = mu_0/1.2 pi [I_2 - I_1] = 4 pi times 10^- 7/1.2 pi [8.5 - 1.5] = 28/1.2 times 10^- 7 = 23.33 times 10^- 7 Vertical-bar B Vertical-bar = 2.333 mu T i am also getting the 2.33 mu t please do not go to down vote Plz comment below for to help me for two update answer k^2 = (1.2)^2 + (1.2)^2 k^2 = 2 (1.2)^2 k = 1.652 tan Theta = 1.2/1.2 = 45 B_x = B_I_2 1/squareroot 2 x
