A 2.0-cm length of wire centered on the origin carries a 20-A current directed in the positive y direction. Determine the magnetic field at the point x = 5.0 m on the x-axis.

field strength = 8x10^-8T

Explanation:

At a distance r from a long current carrying conductor of current I,

B = uL/2¶r

Where u = 4¶x10^-7 H/m = permeability of free space.

r = 5m

I = 20A

B = (4¶x10^-7 x 20)/2¶x5

B = 8x10^-8T
