Two wires parallel to each other and seperated by a distance
d carry different currents; they exert a force with
magnitude F on each other.
(a) The wires carry current in the same direction. If the current
carried by one of the wires is quintupled and the distance between
the wires is divided by three, then what will the force's magnitude
be (as a multiple of F) and will it be repulsive or
attractive?
F ---Select--- attractive repulsive
(b) The wires carry current in opposite directions. If the
current carried by both wires is quadrupled and the distance
between the wires is divided by three, then what will the force's
magnitude be (as a multiple of F) and will it be repulsive
or attractive?
F ---Select--- attractive repulsive

Two long, straight, parallel wires separated by a distance d carry currents in opposite directions as shown in the figure. The bottom wire carries a current of 6.0 A. Point C is at the midpoint between the wires and point O is a distance 0.50d below the 6-A wire as suggested in the figure. The total magnetic field at point O is zero tesla. a. Determine the value of the current, I, in the top wire. Determine the magnitude of...
Two wires are placed parallel to each other as shown. They carry currents of 20 A and 5.0 A respectively in opposite directions. The wires are separated by 0.50 m. mc005-1.jpg (a) What is the strength of the magnetic field at a point midway between the two wires? (LaTeX: \mu_0 μ 0 = 4LaTeX: \pi π × 10-7 T · m/A) (b) What is the magnitude of force per length between the two wires?
Two very long, straight, parallel wires separated by distance d carry currents of magnitude I in opposite directions. Find the magnetic field at a point equidistant from the lines, with a distance 2d from each line. Draw a diagram showing the direction of the magnetic field. One very large conducting plate coincides with the x-y plane.
3. Parallel wires carrying currents will exert forces on each other. 2098 Each wire produces a magnetic field, which influences the other wire. When the currents in both wires flow in the same direction, then the force is attractive. When the currents flow in opposite directions, then the force is repulsive. You can see this in the You Tube video. Two parallel wires that are 14 mm apart each have a current of 2.8 amps. Part Description Answer Chk History...
