Question

Two long, straight, parallel wires carry current. The first wire carries I1 = 3 A to the right and the second carries I2 = 5 A to the left. The force per length each wire exerts on the other is of magnitude 5 × 10−6 N/m.

(a) Sketch the situation. On your sketch indicate the directions of the magnetic fields produced by each wire and the direction of the force exerted on each wire. Determine the distance between the wires.

(b) What is the magnetic field (magnitude and direction) at a point halfway between the wires?

(c) What is the magnetic field (magnitude and direction) current 1 produces at current 2?

Two long wires are aligned parallel to each other and separated
by 20.0 cm. One wire carries a current, I1 and
the other carries a current I2 in the opposite
direction, where for the current magnitudes, I2
= 3 I1. The magnitude of the magnetic field at
a point midway between the wires is4.0 μT. Determine
I2.

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

Two parallel long, straight wires are separated by 3.00 cm. One
of them carries a current of 2.00 A. The magnetic field at a point
halfway between the two wires has magnitude 5.00×10^(−5)T. What is
the current in the second wire if its direction is the same as in
the first wire?

opposite to that in the first wire?
Express your answer with the appropriate units.

Consider two long straight
wires parallel to each other. The wire A on the left has a
current of I1= 3 A and is separated by 5 m from the wire
B on the right that carries I2= 2 A of current. The currents
are flowing in the same direction as in the figure.

Three infinite straight wires are fixed in place and aligned
parallel to the z-axis as shown. The wire at (x,y) = (-17.5 cm, 0)
carries current I1 = 3.2 A in the negative z-direction. The wire at
(x,y) = (17.5 cm, 0) carries current I2 = 1 A in the positive
z-direction. The wire at (x,y) = (0, 30.3 cm) carries current I3 =
7.7 A in the positive z-direction.
