A long straight wire parallel to the y-axis carries a current of I1 = 3.6 A in the -y-direction crosses the x-axis at a point that is 12.0 cm to the left of the origin. Another long straight wire that is 8.40 cm to the right of the origin on the x-axis carries a current of I2 = 4.2 into the page.
a) What is the net magnetic field (magnitude and direction) produced by these currents at the origin?
b) A proton moves through the origin traveling along the x-axis to the right. At the moment the proton is at the origin, what is the magnetic force on the proton?

A long, straight wire carrying a current of I1 =5.0 A perpendicular to the xy plane (page on a table) intersects the x-axis at the origin and points +z direction (out of page). A second, long wire carrying I2 = 12 A intersects the x-axis at x= 6.0 cm and points -z direction (into the page). Find the direction and magnitude of the net magnetic field due to these two currents at (x=0, y= 8.0 cm). First draw a neat...

A long, straight wire lies along the x-axis and carries current I1 = 2.50 A in the +X-direction. A second wire lies in the xy-plane and is parallel to the x-axis at y = +0.900 m. It carries current 12 = 6.00 A, also in the +3-direction.Part A In addition to y→∞, at what point on the y-axis is the resultant magnetic field of the two wires equal to zero?
A long, straight wire carrying a current I1 is placed on a horizontal table in front of you and the direction of the current points +x axis. The magnetic field produced by the current I1 at a point 5 cm above the wire is 0.2 T. A second parallel wire carrying a current I2 = 3I1 is placed 10 cm above the first wire and the direction of the current also points +x axis. What is the direction of the...
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

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

Three infinite straight wires are fixed in place and aligned parallel to the z-axis as shown. The wire at (x,y) = (-22 cm, 0) carries current I1 = 3.1 A in the negative z-direction. The wire at (x,y) = (22 cm, 0) carries current I2 = 0.7 A in the positive z-direction. The wire at (x,y) = (0, 38.1 cm) carries current I3 = 6.3 A in the positive z-direction. 1.

Four long straight parallel wires are oriented perpendicular to
the x-y plane and carry currents I1, I2,
I3 and I4. The magnitudes of the currents are
all identical and equal to 4.015 A. Current I3 is into
the x-y plane (i.e. into the screen), whereas each of the other
three currents are all out of the x-y plane(i.e. out of the screen)
as shown below. Each of the wires is a distance of 2.987 cm from
the origin as measured...
