Question

Two long parallel wires are 4.0 cm apart. Each wire carries the current 10 A in the same direction. Find the magnetic field halfway between the wires.

Answer #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?
What is the current in the second wire if its direction is
opposite to that in the first wire?
Express your answer with the appropriate units.

Two parallel long, straight wires are separated by 3.50 cm . One
of them carries a current of 2.00 A. The magnetic field at a point
halfway between the two wires has magnitude 6.00×10−5T .
a)What is the current in the second wire if its direction is the
same as in the first wire?
b)What is the current in the second wire if its direction is
opposite to that in the first wire?

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....

Two long wires are aligned parallel to each other and separated
by 20.0 cm. One wire carries a current, I1and
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 is 4.0 μT. Determine
I2.

(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...

Two long parallel wires 45.6 cm apart are carrying currents of
13.0 A and 23.0 A in the same direction. What is the magnitude of
the magnetic field halfway between the wires?

Two long parallel wire each carry 2.5 A in the same direction,
with their centers 1.5 cm apart.
A. Find the magnetic field halfway between the wires.
B. Find the magnetic field at a point in the same plane as the
wires, 1.5 cm from one wire and 3.0 cm from the other.
C. Find the force of interaction between the wires, and tell
whether it’s attractive or repulsive.

(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 parallel long, straight wires are separated by 3.00 cmcm.
One of them carries a current of 2.00 AA. The magnetic field at a
point halfway between the two wires has magnitude
5.00×10−5T5.00×10−5T. 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?
Express your answer with the appropriate units.

Two 1-meter long vertical, parallel wires 12.5 cm apart each
carry a current. The first wire carries 31 Amps upward. If it
exerts an attractive force of 5.1 x 10- 4 N on the second wire,
what is the magnitude and direction of the current in the second
wire?
