Question

Two parallel wires are separated by 7.00 cm, each carrying 2.65
A of current in the same direction.

(a) What is the magnitude of the force per unit length between
the wires?

(b) Is the force attractive or repulsive?

Answer #1

Two long, parallel wires separated by 2.80 cm carry currents in
opposite directions. The current in one wire is 1.30 A, and the
current in the other is 3.35 A.
(a) Find the magnitude of the force per unit length that one
wire exerts on the other.
(b) Is the force attractive or repulsive?
attractiverepulsive

Wires carrying current can attract or repel each other. two
wires are parallel but carry current in opposite directions.
I1 = 5 A,
I2 = 8 A
Distance between wires = 30 cm
Find the force per unit length on either wire
A.) 3.4 x 10^-5 N attractive
B.) 2.7 x 10^-5 N repulsive
C.) 2.7 x 10^-5 N attractive
D.) 7.2 x 10^-5 N repulsive
E.) 7.2 x 10^-5 N attractive

Determine the magnitude and direction of the force between two
parallel wires 15 m long and 4.0 cm apart, each carrying 15 A in
the same direction.
(SELECT ONE OF THE FOLLOWING):
The force on each wire will be repulsive. The force on each wire
will be attractive. The wires will not interact.
Part B: Determine the magnitude of the force between two
parallel wires.

Two long straight current-carrying wires run parallel to each
other. The current in one of the wires is 4.9 A, their separation
is 3.6 cm and they repel each other with a force per unit length of
2.5 10-4 N/m.
(a) Determine the current in the other wire.____ A
(b) Determine if the currents are in the same or opposite
direction.
(c) Determine what will happen if the direction of one current
is reversed and tripled. (Select all that apply.)...

(a) Consider two parallel wires running 2 cm apart. Each wire
carries a current of 10 A
running in the same direction. Sketch the set-up and calculate
the magnitude
of the force per unit length between the wires. Indicate the
direction of the forces
acting on the wires in your sketch.
(b) Consider that this experimental set-up was used to
originally define a current of 1 A in magnitude,
i.e a current of 1 A corresponds to the current that...

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...

(a) Consider two parallel wires running 2 cm apart. Each wire
carries a current of 10 A running in the same direction (such a
current is of the order of a large household current to power
electrical devices). Sketch the set-up and calculate the magnitude
of the force per unit length between the wires. Indicate the
direction of the forces acting on the wires in your sketch.
(b) If you are surprised by the round number consider that this
experimental...

Two long parallel wires, each carrying a current of 12 A, lie at
a distance of 4 cm from each other. What is the magnetic force per
unit length exerted by one wire on the other? The magnetic force
per unit length exerted by one wire on the other is ×10-4 N/m

Two long, parallel wires are separated by a distance of 2.80 cm
. The force per unit length that each wire exerts on the other is
3.40×10−5 N/m , and the wires repel each other. The
current in one wire is 0.520 A .
a) What is the current in the second wire?

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?
What is the current in the second wire if its direction is
opposite to that in the first wire?
