Two loops of wire are parallel to each other and close to each other. They have current passing through them in opposite directions. If the loops are allowed to move what will happen?
Homework Answers
current passing through them in opposite directions will repel each other. so the two wire will move in the opposite direction.

For this station, you have two coils of wire (each with different numbers of loops), a magnet, some connecting wires, and a galvanometer. A galvanometer is an ammeter that measures very small currents (micro-amperes) and indicates the direction of that current. Understanding how the meter behaves is important here, because you’re going to use the meter to determine/measure current—including its direction. For this galvanometer, when (conventional) current enters the terminal on the right (as viewed when reading the dial), the...

We have two very long wires, which are parallel to each other pointing to the right in front of us. The pair of wire is horizontal. The wire closest to us carries a charge per unit length of 1mC/m and the other the opposite charge. The two wires are 1m apart and both move together at 100m/s along the wire to the right. We are looking at what happens in the middle region of the two wires (not the end)....

Two long wires, 4cm apart, are parallel to
each other. The wires have an equal amount of current
I1=I2= 20Aflowing through them. Points
P and R are a distance a = 2.5 cm above the top wire and
below the bottom wire respectively. Point Q is halfway between the
two wires.
What is the net magnetic field strength at points P, Q, and
R?
Q. 4 cm.
