The magnetic field of an infinitely long straight wire can be obtained by applying Ampere's law. The expression for the magnetic field is. Show. Once the magnetic field has been calculated, the magnetic force expression can be used to calculate the force.
What is the force between two parallel wires?
This force between two current carrying wires gives rise to the fundamental definition of the Ampère: If two long parallel wires 1m apart each carry a current of 1A, then the force per unit length on each wire is 2×10−7N/m.
What is the force per unit length between the two wires?
This force between two current carrying wires gives rise to the fundamental definition of the Ampère: If two long parallel wires 1 m apart each carry a current of 1 A, then the force per unit length on each wire is 2 x 10- 7 N/m.
Which rule can be used to find the force between the two conductors?
The Fleming's left hand rule can be used to determine the direction of the force, magnetic field and current. A left hand can be held, so that the thumb, first finger and second finger are held mutually perpendicular to each other. The thumb represents the direction of Motion resulting from the force on the conductor.

How do u calculate force?
Force exerted by an object equals mass times acceleration of that object: F = m * a.
What is Fleming's left hand rule used for?
Fleming's left-hand rule is used to find the direction of the force acting on the current carrying conductor placed in a magnetic field.
Why does a force act on a wire?
A wire carrying a current creates a magnetic field . This can interact with another magnetic field, causing a force that pushes the wire at right angles. This is called the motor effect.
What is the force per unit length of each wire?
The force per unit length can then be calculated using the known currents in the wires: Fl=(4π×10−7T⋅m/A)(5×10−3A)2(2π)(5×10−2m)=1×10−10N/m.
What is the force between two perpendicular current carrying wires?
If the wires are perpendicular however, the force between them is 0.
How do you find force per length?
Summary. The force between two parallel currents I1 and I2, separated by a distance r, has a magnitude per unit length given by Fl=μ0I1I22πr.
What is the magnetic force between two parallel current carrying conductor?
Force between two parallel Current carrying conductor Thus, from the two studies, we can say that any two current carrying conductors when placed near each other, will exert a magnetic force on each other.
What is the magnetic force per unit length exerted by one wire on the other?
Hence, force per unit length is F=2πbμi.
Which rule is used to find the force on a current carrying wire placed in a magnetic field?
Fleming's right hand rule is used to determine the direction of force acting on a current carrying wire placed in a magnetic field.
Which rule is used to find the magnetic force?
We can remember this diagram using the right-hand rule. If you point your pointer finger in the direction the positive charge is moving, and then your middle finger in the direction of the magnetic field, your thumb points in the direction of the magnetic force pushing on the moving charge.
What is net force formula?
Net force is the sum of all forces acting on an object. The net force can be calculated using Newton's second law, which states that F = ma, where: F is the net force. m is the mass of the object. a is acceleration.
What is the difference between Fleming's left hand rule and Fleming's right-hand rule?
Fleming's left-hand rule gives the direction of magnetic force acting on a conductor whereas Fleming's right-hand rule is used to find the direction of induced current.
What is right-hand rule 10th thumb?
Right Hand Thumb Rule: If a current carrying conductor is imagined to be held in your right hand such that the thumb points along the direction of current, then the direction of the wrapped fingers will give the direction of magnetic field lines.
How does length of wire affect force?
The magnitude of the force on a current carrying conductor increases when the strength of the magnetic held is increased. The magnitude of the magnetic force also depends on the length of the wire in the magnetic field. The longer the wire in the magnetic field, the larger the force on the wire as shown in Figure.
What is force over volume?
The force density, or force per unit volume, f, is the net force (F) on a region of matter divided by the volume (V) that contains it: f = F/V.
What is force per unit area called?
Pressure is defined as force per unit area. The standard unit for pressure is the Pascal, which is a Newton per square meter.
What is the nature of force between two parallel current carrying wires in same direction?
The force between the two parallel conductors is attractive in nature if the current is flowing in same direction in both the conductors whereas the force is repulsive if the current is flowing in opposite direction in the conductors.
What is magnetic field formula?
Magnetic field magnitude = \frac{(permeability of free space) (current magnitude)}{2\pi (distance)} B = \frac{\mu_{0}}{2\pi r}.
What is magnetic force per unit length?
Magnetic force per unit length on the wire is given as: f= BI sinΩ¸ = 0.15 x 8 x 1 x sin30° = 0.6 N m-1. Hence, the magnetic force per unit length on the wire is 0.6 N m-1.
What is magnetic force per unit length experienced by wire C?
The force on wire C due to B and A is. F=FB+Fc=4Πμ02d2II+4Πμ0(2d+d)2(I)(I)=4Πdμ02I2(1+31)=4Πdμ02I2×(34)=3ΠdμI.
What is Fleming's right hand law?
Fleming's right-hand rule gives which direction the current flows. The right hand is held with the thumb, index finger and middle finger mutually perpendicular to each other (at right angles), as shown in the diagram. The thumb is pointed in the direction of the motion of the conductor relative to the magnetic field.
How are the force on the wire and the force on the magnet related?
The magnetic force on a current-carrying wire is perpendicular to both the wire and the magnetic field with direction given by the right hand rule.
