A long straight wire X carries 3 A current horizontally to the
right. Another long straight wire Y, which is 20 cm below wire X,
carries 2 A current also horizontally to the right. (a) Calculate
the magnitude of the magnetic field midway between the two wires.
(b) Calculate the magnitude of the magnetic field at a point 10 cm
below wire Y.

A) Determine the magnitude of the magnetic field midway between
two long straight wires 2.50 cm apart when one wire carries 4.40 A
and the other carries 12.6 A. Assume these currents are in the same
direction. B) Determine the magnitude of the magnetic field when
these currents are in opposite directions.

Two long straight wires are parallel and carry current in
opposite directions. The currents in the wires are 8.0 A for the
left wire upward and 12 A for the right wire downward. The wires
are separated by 0.40 cm.
A. The magnetic field due the left wire in mT (milli-tesla) at a
point midway between the wires is:
B. The direction of the magnetic field of the left wire carrying
8.0 A at a point midway between the wires...

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 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 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.
