A current carrying conductor creates a magnetic field around it, which can be comprehended by using magnetic lines of force or magnetic field lines. The nature of the magnetic field lines around a straight current carrying conductor is concentric circles with centre at the axis of the conductor.
What is magnetic field due to a current carrying conductor?
The magnetic field produced due to a current-carrying conductor has the following characteristics: It encircles the conductor. It lies in a plane perpendicular to the conductor. Reversal in direction of current flow reverses the direction of the field.
What type of magnetic field pattern do we get around a straight conductor carrying current?
When electric current is carried by a straight wire, it produces magnetic field lines in the form of concentric circles.
What is the strength of magnetic field around a current carrying conductor?
the strength of the magnetic field around a current carrying conductor is directly proportional to the current but inversely proportional to the distance from the wire.
Does current carrying conductor produces electric field?
The electric field inside a current carrying conductor is zero be because the charges are distributed on the surface of the conductor. But, magnetic field is created around the current carrying conductor. The moving charges create a magnetic field around the conductor.
What kind of magnetic field is produced by a current carrying circular field?
Answer. Answer: At the centre of the circular loop, The magnetic field lines are straight. Each segment of circular loop carrying current produces magnetic field lines in the same direction with in the loop.
What are the factors affecting magnetic field in a straight conductor?
Greater the current in the conductor, stronger will be the magnetic field will be produced. Strength of the magnetic field is inversely proportional to the distance from the wire. Greater the distance from the current carrying conductor, weaker will be the magnetic field.
What is the shape of the magnetic field lines around a long straight current carrying wire?
The field around a long straight wire is found to be in circular loops. The right hand rule 2 (RHR-2) emerges from this exploration and is valid for any current segment—point the thumb in the direction of the current, and the fingers curl in the direction of the magnetic field loops created by it.
How will you describe the magnetic field around a straight current carrying wire?
The magnetic field around a straight current-carrying wire is strongest near and around the wire. … However as the radius(r) increases, which is the distance from the wire, the magnetic field decreases. It can be viewed from the image that the magnetic field’s direction is found by curling hand around the wire.
What is magnetic field due to an infinite linear current carrying conductor?
Magnetic field due to an infinitely long straight current carrying wire – definition. B=(2πr)μ0I where B is the magnitude of magnetic field, r is the distance from the wire where the magnetic field is calculated, and I is the applied current.
How will you prove that current carrying conductor produces the magnetic field?
If two straight wires are placed side by side, the magnetic fields produced by the currents in them will combine to form a resultant field. (a) Figure shows the magnetic field for two straight parallel wires carrying current in the same direction. The wires attract with each other. … The wires repel with each other.
Why electric field outside a current carrying conductor is zero?
There is no E field outside the conductor due to electrons because the conductor is not charged–this means there exist an equal number of protons to every electron in the conductor. If the conductor was charged, then there would be E field outside the conductor due to that charge.
Why must there be an electric field inside a current carrying conductor?
Suggest why there must be an electric field inside a current-carrying conductor. To have a current, electrons must be accelerated along the wire and so an electric force must act on them. This is provided by the electric field. … Gravitational force is always attractive while electric force can be repulsive.
How is electric field produced?
The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell’s equations and the Lorentz force law.
