Question

The problem reads

"We are given two long straight wires both perpendicular to the page. One with current 2 A running into the paper and the second with a current of 2 A running out of the paper. Determine the magnitude and direction of the total magnetic field at the point P shown. "

sorry if my work gets in the way of the picture, im trying! Thanks in advanced

Explanation / Answer

B1 = uoi/2pir1 = 2e-7*2/sqrt 2 = 2.828e-7

B2 = 2e-7*2/1 = 4e-7

Bx = 2.828e-7 cos 45 degree - 4e-7 = -2e-7

By = - 2.828e-7 sin 45 degree =  -2e-7

Bnet = 2.828e-7 = 2.828*10^-7 T answer

at an angle of 225 degree with positive x axis or towards left wire
