[Physics] Magnetic Field due to one current

with a positive current flowing in the k direction. Your current is negative, which means it is flowing into the paper, that is, in the -k direction.) Find the magnetic field at a point 3.......
A current of -3.55 A is located at the origin. (The current flows parallel to the z axis, with a positive current flowing in the k direction. Your current is negative, which means it is flowing into the paper, that is, in the -k direction.) Find the magnetic field at a point 3.11 cm along the y axis, that is, at the point (0.00, 3.11) cm.

Enter the x and y components of the field:

Using the first right hand rule, the magnetic field for a point on the y-axis is to the right, So By = 0

Assuming an infinitely long current Bx.2 Pi y = muzero I

so Bx = muzero x I /(2 Pi y) with y = .0311 m and muzero = 4 Pi x 10^-7

so Bx = 2 x 10^-7 x 3.55 / 0.0311 Tesla
