Question

the cross section of five long parallel wires, separated by a distance d = 10 cm and have lengths of 21.0 m. Each wire carries a current of 5.6 A. Currents 1, 3, and 5 are out of the page, while currents 2 and 4 are into the page. Each wire experiences a magnetic force due to the other wires. What is the magnitude and direction of the net magnetic force on wire 1?

Answer #1

As we know wires which have current in same direction attract each other and the wires which have current Repel each other.

So wires 3 and 5 attract wire 1 and wires 2 and 4 Repel wire 1 so

Force on wire 1 due to all wires

F = - F12 + F13 - F14 + F15

= - μoI2L/2πd + μoI2L/2π(2d) - μoI2L/2π(3d) +μoI2L/2π(4d) = μoI2L/2πd(-1 +1/2 - 1/3 + 1/4)

2×10-7×(5.6)2×21/0.1(-0.58)

= - 7.68×10-4 T

Direction = away from the wire becuare Repulsive force is more then attractive force.

two long straight wires are perpendicular to the page and
separated by distance d1 = 8.8 cm. Wire 2 carries a current of 3.0
A into the page. What are the magnitude and direction of the
current in wire 1 if the net magnetic field due to the two currents
is zero at point P located a distance d2 = 12 cm from wire 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.

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?

As shown in the figure below, two long parallel wires (1 and 2)
carry currents of I1 = 3.32 A and I2 = 4.50 A in the direction
indicated. Two parallel wires point into the page. They are a
distance d apart from each other, with the left wire labeled I_1 at
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
a distance d...

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 .

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?
