When the current goes the same way in the two wires, the force is attractive . When the currents go opposite ways, the force is repulsive. You should be able to confirm this by looking at the magnetic field set up by one current at the location of the other wire, and by applying the right-hand rule.
Why do two wires attract?
When the currents flow in the same direction the magnetic field will be opposite and the wires will attract. ... If electrons in both wires are moving in the same direction they see the same number of electrons in the other wire (because they are moving at the same speed.)
How do you find the magnetic field between two wires?
The dimensional formula of Magnetic field is given as M1 T-2 I-1 .
Do wires attract each other?
Note that two wires carrying current in the same direction attract each other , and they repel if the currents are opposite in direction.
What is repulsion and attraction?
Repulsion is a force between two similar or like charges , while Attraction is a force between two dissimilar or unlike charges. ... Example: The force between two electrons (negative charge), while In attraction, the two charges of dissimilar nature are pulling toward each other.
How do you find the force between two wires?
Magnetic force between wires equation
d is the distance between the wires; F / L is the force per unit length acting on each wire; μ0 is the permeability of free space which have constant value μ0 = 4 * π * 10^(-7) [T * m / A] .
What happens when two current carrying wires are placed next to each other?
So if you have two current-carrying, parallel wires with magnetic fields circling around them in the same direction, they will attract each other , as shown in the tutorial; at the point at which their respective magnetic fields intersect, they are traveling in opposite directions, and opposites attract.
What force is acting between two parallel wires carrying current in the same direction?
Thus, when two parallel wires carry current in the same direction, they exert equal and opposite attractive forces on each other .
What happens when the current of the two wires are in opposite direction?
If wires carry current in the opposite direction, the wires will repel each other .
What is the force of repulsion?
Repulsion is’ a movement between two charges that are identical or similar. The force of two electrons between them (negative charge) . ... ‘ The two charges of a different type draw against one another. Magnetism, operating at a distance, is a force of desire or repulsion.
What causes attraction and repulsion?
When two opposite magnetic poles
What is force of attraction?
The force of attraction is a force that draws the body close to it due to an attraction . ... These are the electric force, magnetic force, electrostatic force, gravitational force, and electromagnetic force. Gravitational force is a well-recognized force that attracts the body towards it despite the distance.
Why do 2 parallel conductors exert force on each other?
Explain Why Two Current Carrying Parallel Conductors Attract. ... Ans: When the flow of the currents is in the same direction, the magnetic field will be opposite and the wires will attract .
What is Ampere’s right hand rule?
(b) Right hand rule 2 states that, if the right hand thumb points in the direction of the current, the fingers curl in the direction of the field . This rule is consistent with the field mapped for the long straight wire and is valid for any current segment.
Is the force between the wires attractive or repulsive?
. The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions . This force is responsible for the pinch effect in electric arcs and plasmas. The force exists whether the currents are in wires or not.
