A 1.2-m 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= 5.0m on x-axis.

a. 1.6 nt in the negative z direction
b. 1.6 nt in the positive z direction
c. 2.4 T in the positive z direction
d. 2.4 nt in the negative z direction
e. None of the above

Answer:

None of the above

Explanation:

The formula of the magnetic field of a point next to a wire with current is:

B = 2Ă—10^(-7) Ă— ( I /d)

I is the intensity of the current.

d is the distance between the wire and the point.

â—Ź B = 2*10^(-7) Ă— (20/5) = 8 Ă—10^(-7) T
