Question

two long straight wires are in the xy plane and parallel to
the x axis. one wire is at x=10 cm and the other is on the y-axis.
the current in each wire is 1.5 A and are antiparallel. the
magnetic field on the x-axis at x=20 cm is...?

Answer #1

Two long straight wires carry currents perpendicular to the
xy plane. One carries a current of 45 A and passes through
the point x = 5.5 cm on the x axis. The second
wire has a current of 80 A and passes through the point y
= 4.3 cm on the y axis. What is the magnitude of the
resulting magnetic field at the origin?

Two long, parallel, current-carrying wires lie in an
xy-plane. The first wire lies on the line y =
0.310 m and carries a current of 25.5 A in the +x
direction. The second wire lies along the x-axis. The
wires exert attractive forces on each other, and the force per unit
length on each wire is 300 µN/m. What is the
y-value (in m) of the line in the xy-plane where
the total magnetic field is zero?

Three long wires are all parallel to each other and are all in
the xy plane. Wire 1 runs along the y axis and carries a current of
1.68 A in the +y direction. Wire 2 runs along the x = 25.0 cm line
and carries a current of 4.06 A in the −y direction.

it carries a certain current (to be determined later) each wire...

Three long wires are all parallel to each other and are all in
the xy plane. Wire 1 runs along the y axis and

line and carries a current of 4.00 A in the ?y
direction.

Two long, straight wires, one above the other, are seperated by
a distance 2a and are parallel to the x?axis. Let the +y?axis be in
the plane of the wires in the direction from the lower wire to the
upper wire. Each wire carries current I in the +x?direction. Find
B? - the net magnetic field of the two wires at the following
points in the plane of the wires.
a)Midway between the
wires. Express your answer in
terms of...

Two parallel long, straight wires are separated by 3.50 cm . One
of them carries a current of 2.00 A. The magnetic field at a point
halfway between the two wires has magnitude 6.00×10−5T .
a)What is the current in the second wire if its direction is the
same as in the first wire?
b)What is the current in the second wire if its direction is
opposite to that in the first wire?

Three long, straight wires all exist in the xy-plane. One
carries a current of 3.30 AA in the positive y-direction through
the point x=-3.40 mm . The second carries a current of 19.8 AA in
the positive y-direction through the point x=9.00 mm . The third
wire carries a current in the negative y-direction and goes through
the point x=4.00 mm . What current does the third wire carry if the
magnetic field at the position x=1.25 mm is exactly...

In the figure, five long parallel wires in the xy plane are
separated by distance d = 6.30 cm, have lengths of 10.0 m, and
carry identical currents of 3.52 A out of the page. Each wire
experiences a magnetic force due to the other wires. What is the
magnitude of the net magnetic force on (a) wire 1, (b) wire 2, (c)
wire 3, (d) wire 4, (e) wire 5?

Point P is midway between two long, straight, parallel
wires that run north-south in a horizontal plane. The distance
between the wires is 1.70 cm. Each wire carries a current of 4.50 A
toward the north. Find the magnetic field at point P.

A long wire carrying a 4.0 A current perpendicular to the
xy-plane intersects the x-axis at x=−2.2cm. A second, parallel wire
carrying a 2.8 A current intersects the x-axis at x=+2.2cm
A) At what point on the x-axis is the magnetic field
zero if the two currents are in the same direction?
B) At what point on the x-axis is the magnetic field
zero if the two currents are in opposite directions?
