respectively, in opposite directions. The force per unit length in
N/m of one wire on the other is:

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.

Consider two very long conducting parallel wires carry currents
in opposite directions such that one is triple of the other. The
distance between wires is 30 cm. The magnetic field at points on a
line between the wires, and at a distance of 5 cm from the wire
carrying the smaller current, is 2.5×10-5 T. a) Draw a diagram of
the situation. Assume the wires are placed in the x-direction. Draw
the direction of the magnetic field at points on...

Wires carrying current can attract or repel each other. two
wires are parallel but carry current in opposite directions.

not dc currents
Please explain

The two wires shown in the figure carry currents of I = 4.08 A
in opposite directions and are separated by a distance of
d0 = 8.08 cm. Calculate the net magnetic field at a
point midway between the wires. Use the direction out of the page
as the positive direction and into the page as the negative
direction in your answer.Calculate the net magnetic field at point
P1 - that is 9.87 cm to the right of the wire...

a) Two long, parallel wires are separated by a distance 3.00 cm
and are repelling each other with a force per unit length of
2.00×10−5 Nm−1 . If a current of 0.600 A is
flowing along one wire, what is the current in the other wire? Are
the currents flowing in the same directions or in opposite
directions?
b) Two long, parallel wires are hanging by regularly spaced,
4.00 cm long cords from a common axis. The wires have a...
