Question

Two 2 m long parallel wires separated by 5 m exert an attractive force on one another. If the magnitude of the current in one wire is I1=I1=4 A, and the magnitude of the magnetic field due to wire 2 at the location of wire one is 1.3875 T, what is the magnitude of the current in wire 2 (I2I2) in MA? Enter your answer as a number only, to 2 decimal places.

Answer #1

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, parallel conductors separated by 14.0 cm carry
currents in the same direction. The first wire carries a current

plane of the page.)

sure to draw a picture and...

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.

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?

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

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
