Two long, parallel conductors, separated by 13.0 cm,
carry currents in the same direction. The first wire carries a
current I1 = 7.00 A, and
the second carries I2 = 8.00 A. (See
figure below. Assume the conductors lie in the plane of the
page.)
Two long, parallel conductors lie in
the x y plane of
the x y z coordinate
space. The first lies along the x-axis. The
second lies above the x-axis, parallel to
the x-axis. The first carries
current I1, the second
current I2, both flowing in
the +x-direction.
(a) What is the magnetic field created
by I1 at the location
of I2?
(b) What is the force per unit length exerted
by I1 on I2?
(c) What is the magnetic field created
by I2 at the location
of I1?
(d) What is the force per length exerted
by I2 on I1?
