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 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.

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.

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 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.

Two long straight wires are parallel and 8.4 cm apart. They are
to carry equal currents such that the magnetic field at a point
halfway between them has magnitude 240 µT. (a) Should the currents
be in the same or opposite directions? (b) How much current is
needed?
