Four long, parallel conductors carry equal currents
of I = 4.80 A. The figure below is an
end view of the conductors. The current direction is into the page
at points A and B and out of
the page at C and D.
A cross-sectional illustration shows
four long, parallel conductors carrying current into and out of the
plane of the page. They are arranged so that each conductor lies at
the corner of a square of side ℓ.
Point P is at the center of the square.
(a)
Calculate the magnitude of the magnetic field at
point P, located at the center of the square of edge
length ℓ = 0.200 m.

(b)
Determine the direction of the magnetic field at
point P, located at the center of the square of edge
length ℓ = 0.200 m.
