Question

Use the Biot-Savart Law (the many-step process) to derive a formula for the magnetic field created at [X,0,0], where X > 5 cm, by a current of 2.00 A that flows in a wire as described here. The wire was originally formed in a circle of radius 5 cm lying in the x-y plane with its center at the origin. Then the semicircle on the +x side was bent down so that it lies in the y-z plane on the -z side. The current in the x-y plane goes clockwise as seen from +z.

Answer 1

A that flows in a wire as described here.

The wire was originally formed in a circle of radius 5 cm lying in the x-y plane with its center at the origin.

Then the semicircle on the +x side was bent down so that it lies in the y-z plane on the -z side.

The current in the x-y plane goes clockwise as seen from +z.

Here,

radius, r = 5 cm = 5 × 10^-2 m

Current, I = 2.00 A

Now
