Question

**Three parallel, long straight wires are carrying
currents into or out of the page. The distance between wires X and
Y is the same as the distance between wires Y and Z. The magnitude
of the current in all wires is the same.**

**Rank the strength (magnitude) of the magnetic field
acting on wire Y from greatest to least.**

**Thank you in advance for your help! If you could, please
explain to me why the answer is what it is. I am trying to
understand the concept but I am utterly lost on this
one.**

Answer #1

Two long parallel wires 45.6 cm apart are carrying currents of
13.0 A and 23.0 A in the same direction. What is the magnitude of
the magnetic field halfway between the wires?

Two long straight wires are parallel and carry current in
opposite directions. The currents in the wires are 8.0 A for the
left wire upward and 12 A for the right wire downward. The wires
are separated by 0.40 cm.
A. The magnetic field due the left wire in mT (milli-tesla) at a
point midway between the wires is:
B. The direction of the magnetic field of the left wire carrying
8.0 A at a point midway between the wires...

Consider two long and parallel current carrying wires that are a
distance 3.00 m away from each other, and carrying 72.0 mA and 33.0
mA currents.
Assume that the origin of the coordinate system is on the 33.0
mA wire and its positive x axis is directed towards the 72.0 mA
wire that is perpendicular to the wires.
a.) If these currents are in the opposite direction, find all
locations where the net magnetic field of the two wires is...

Consider two long and parallel current carrying wires that are a

35.0 mAmA currents.
Assume that the origin of the coordinate system is on the 35.0
mAmA wire and its positive xx axis is directed towards the 77.0

a) If these currents are in the opposite direction, find all
locations where the net magnetic field of the two wires is...

the cross section of five long parallel wires, separated by a
distance d = 10 cm and have lengths of 21.0 m. Each wire carries a
current of 5.6 A. Currents 1, 3, and 5 are out of the page, while
currents 2 and 4 are into the page. Each wire experiences a
magnetic force due to the other wires. What is the magnitude and
direction of the net magnetic force on wire 1?

As shown in the figure below, two long parallel wires (1 and 2)
carry currents of I1 = 3.32 A and I2 = 4.50 A in the direction
indicated. Two parallel wires point into the page. They are a
distance d apart from each other, with the left wire labeled I_1 at
the origin and the right wire labeled I_2 a distance d along the
positive x-axis. There is a point labeled P directly above wire I_1
a distance d...

two long straight wires are perpendicular to the page and
separated by distance d1 = 8.8 cm. Wire 2 carries a current of 3.0
A into the page. What are the magnitude and direction of the
current in wire 1 if the net magnetic field due to the two currents
is zero at point P located a distance d2 = 12 cm from wire 2?

Consider two long and parallel current carrying wires that are a
distance 7.00 m away from each other, and carrying 73.0 mA and 40.0
mA currents. Assume that the origin of the coordinate system is on
the 40.0 mA wire and its positive x axis is directed towards the
73.0 mA wire that is perpendicular to the wires.
Part C If these currents are in the opposite direction, find all
locations where the net magnetic field of the two wires...

Two long wires parallel to the page carry currents. Wire 1 =
1.5A and wire 2 = 1.1A and they are 1.8cm apart. Point P is 2.3 cm
to the right of wire 2. What is the magnitude and direction of the
magnetic field at P? A compass is placed at P, in which direction
does the north needle point?
