Shown at right is a cross-sectional view of two long straight wires that are parallel to one another. One wire carries a current i_0 out of the page, the other carries an equal current i_0 into the page. a. Draw a vector on the diagram to show the direction of the magnetic field, if any, at point P. Explain your reasoning. b. Suppose that a third wire, carrying another current i_0 out of the page, passes through point...
4. Shown at right is a cross-sectional view of two long, straight wires at are parallel to each other, placed near point P. One wire carries a current i, into the page; the other wire is twice as far away from P and carries a current 2i, out of the page. 2i (Hint: The magnetic field from a current-carrying wire is proportional to the current through the wire and inversely proportional to the distance away from the wire.) Draw and...

The figure below shows a cross-section of two long, straight,
parallel wires, where the currents are flowing perpendicular to the
page. Wire 1 carries a current
I1
directed into the page (in the
−z
direction) and passes through the x-axis at
x = +a.
Wire 2 passes through the x-axis at
x = −2a
and carries an unknown current
I2.
The total magnetic field at the origin due to the
current-carrying wires has the magnitude
2μ0I1
(2πa)
. Note that...
The figure below shows two long, parallel wires in
cross-section, and the currents they carry are directed out of the
page. The left wire carries a current ofI1 = 2.96 A,and the right carries a current ofI2 = 3.45 A.The two wires are a distanced = 20.0 cmapart. Point P is the same distance d above
the right wire.Assume the +x-direction is to the right, and the
+y-direction is upward.A cross-sectional end view of two parallel wires carrying

Two long, straight, parallel current-carrying wires are shown below. The wires are parallel to the (the +z-axis points out of the page). The current 3.2 A is flowing in the +2-direction (out of the page), while the current 12-3.2 A is flowing in the z-direction (into the page). The wire abov he origin passes through y- +3.0 cm, the wire below the origin passes through y- -3.0 cm, P is atx +4.0 cm. a) Find all thrce components of the...
Two long straight parallel wires, separated by
d1 = 0.775 cm, are perpendicular to the plane
of the page as shown in Fig. 30-40. Wire 1 carries a current of
5.70 A into the page. What must be the current (magnitude and
direction) in wire 2 for the resultant magnetic field at point
P to be zero? Point P is d2 =
1.85 cm from wire 2.

The picture below shows a cross-sectional view through three
long straight current-carrying wires, which are each carrying
current perpendicular to the page (or the screen). In this problem,
use these values:
the distance: a = 60.0 cm;
the current: I = 3.50 amps.
(a) Calculate the net force per unit length acting on the wire
that carries a current of 3I out of the page,

Two long, straight wires are parallel and 8.5 cm apart. The top wire carries a current of 1.7 A, the bottom wire a current of 3.4 A. (a) If the two currents flow in the same direction, what is the magnitude and direction of the force per unit length of one wire on the other? (b) What is the magnitude and direction of the magnetic field ¼ of the distance between the two wires? You must draw a diagram, show...
In cross section, two long straight wires. The current I = 1.11
A in the wire which is the closest to the point P is out of the
page. d = 4.88 cm, and it is the distance between the wires, and
also the distance from point P to the closest wire.
