When two parallel wires carry currents in same direction what will be the nature of force attractive repulsive between them?
Thus, when two parallel wires carry current in the same direction, they exert equal and opposite attractive forces on each other.
When two parallel wires carry current in the same direction then?
If two parallel conducting wires carry current in the same direction, then they will attract each other.
What happens if the current carrying wire is parallel to the magnetic field?
Force on a current-carrying wire that is parallel to magnetic field will be zero. This is because the magnitude of force depends on the sin of the angle between the direction of current and the direction of magnetic field, so if the current carrying wire is held parallel to the magnetic field, the force will be zero.
What type of force acts between two parallel wires carrying current in the same direction what happens if one of the current is reversed?
When one current is reversed, the force acting between two parallel wires carrying currents becomes repulsive.
How does the force between two wires carrying equal current change if you doubled the current through each wire and doubled the distance between them?
If the distance between two parallel current carrying wires is doubled, what is the force between them? The force acting on one wire due to currents through two wires is inversely proportional to the distance between them. Thus the force becomes 1/2 times if the distance between the wires is doubled.
Where is the magnetic field zero between two wires?
Where are the points where the magnetic field is zero? Solution: Using the right-hand rule again, allows one to see that the magnetic-field contributions from the two wires have opposite signs either above or below the wires, but not between them.
When the direction of current is opposite in two parallel wires placed near each other they will?
It depends on the direction of the currents in both the wires. If the directions of the currents are opposite, then the wires will repel each other. If the directions of the currents are the same, then the wires will attract each other.
Why is there no force when current and magnetic field are parallel?
The simple reason is that by definition, electromagnetic waves travel perpendicular to one another and therefore exert no force on the other. If you have a current traveling north, but a magnetic field traveling east, due to the mathematical cross-product the force will cancel.
Why do two parallel wires carrying currents in opposite directions repel each other?
The direction of magnetic field on the conductor is determined by Fleming’s right hand rule. Thus, gives us that the direction of magnetic field turns out to be opposite to each other. This results in repulsion of the conductors carrying current in opposite directions relatively and vice versa.
What is the direction of force between two parallel wires carrying current in opposite direction?
Two parallel wires carrying current in opposite directions repel and try to move away from each other.
How does wirewire 1 generate a magnetic field?
Wire 1, the left wire in Figure 1, generates a magnetic field that points out of the page on the left side of the wire. This is shown by the circle with a dot in its center. It also generates a magnetic field that points into the page on the right side of the wire. This is shown by the circle with the X in its center.
What is the force between two long straight and parallel conductors?
The force between two long, straight, and parallel conductors separated by a distance r can be found by applying what we have developed in the preceding sections. (Figure) shows the wires, their currents, the field created by one wire, and the consequent force the other wire experiences from the created field.
How do you determine the direction of the magnetic field?
Here, is the radial distance away from the wire, which shows that the magnetic field dies off the further you get from the wire. The direction of the magnetic field may also be determined by the Right Hand Rule. When you use the RHR for a current carrying wire, align your thumb in the direction of the current.
What is the magnetic field produced by a long straight conductor?
The field due to Figure 12.9 (a) The magnetic field produced by a long straight conductor is perpendicular to a parallel conductor, as indicated by right-hand rule (RHR)-2. (b) A view from above of the two wires shown in (a), with one magnetic field line shown for wire 1.
