Why do electric lines of force not pass through conductor?
Ah but they DO! It is the action of electromagnetic lines of force (EMF) passing through a conductor that introduces current in the conductor. This is the basic principle behind electrical power generation.
The question relates to electric lines of force, not magnetic lines of force. Electric lines of force radiate perpendicularly from electric charge. As like electric charges distribute themselves evenly over the surface of a conductor, the electric lines of force radiate away from the surface of that conductor.
1. Electric field lines of force originate from the positive charge and terminate at the negative charge. 2. Electric field lines of force can never intersect each other. 3. Electric field lines of force are not present inside the conductor, it is because electric field inside the conductor is always zero. 4. Electric field lines of force are always perpendicular to the surface of conductor. 5. Curved electric field lines are always non-uniform in nature.
-- Form a continuous circuit out of a conducting material. -- Move the conductor through the magnetic field, at an angle to the magnetic 'lines of force'.
When a conductor cuts magnetic lines of force, there is a voltage induced in the conductor. This is the basis of generators and motors.
When lines of force are cut by a conductor you have electromagnetic induction. A metallic wire can be used as the conductor.
to save the static character of conductor in the presence of electric field
electric lines of force are imaginary lines defined by the paths traced by unit charges placed in an electric field. Lines of force are everywhere parallel to the electric field strength vector. Their principal use is as a convenient means of picturing the geometry of an electric field.
No. They are are of different nature.
the lines of force are not real. these lines of force are imaginary lines. so we can not touch it.
Under an electric field, magnitude and direction of electric intensity is different in every point.If the electric intensity can be defined through a closed line (direction of electric intensity will be along the tangent of any point of that line)this is called electric lines of force. Electric lines of forces passing through an closed electric surface perpendicularly, is called electric flux.
Presumably, you are asking what happens when a conductor 'cuts' lines of magnetic flux? If so, then a voltage is induced across the ends of that conductor.
Changing the amount of magnetic field (known as "flux") through a conductor exerts a force on charged particles (electrons in the wire). A change in magnetic field strength in a region of space induces an electric field which circles the magnetic field lines, surprisingly whether or not there is a conductor there or not. It turns out that magnetism and electricity are inherently linked, they are kind of manifestations of the same thing. If "something"… Read More
The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the?
The speed of the conductor through the magnetic field, which translates into the number of magnetic lines of force the conductor can cut per unit time, will determine the magnitude of the voltage induced in the conductor. As an additional factor, if a longer piece of wire can be moved through the magnetic field, it will induce more voltage as well. The more speed we can put on the conductor, and the more of the… Read More
A conductor such as a metallic wire.
An electric current is the movement of the conduction band electron "gas" in a conductor. This can be induced in various ways: Application of a voltage difference across the conductor. Having magnetic flux lines "cut through" the conductor, which will push the electron "gas" perpendicular to the plane the flux lines "cut". Connecting the conductor to 2 dissimilar metals and placing the metals in an electrolyte. Corrosion of one of the metals will cause current… Read More
cutting through magnetic lines of force produce electric current.
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are… Read More
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
The electric lines of force never cross each other because electric field has only one direction at a given point. The direction of electric field depends upon the tangent drawn at a single point.
The "lines" of latitude, longitude, reasoning, electric fields, and magnetic fields are imaginary.
Magnetic induction. If you have conductor, then there are these free electrons bouncing back and forth between the atoms. They move in random directions and there is no unified movement which we could detect as electric current. From the Lorentz force of a charge moving through a magnetic field, we have the force as F = qv x B. Where v and B are vectors. The force will be perpendicular to both the velocity and… Read More
There is no substance. Michael Faraday called them 'Lines of Force'. These imaginary lines run from the North to South poles of a magnet and can be concentrated by channeling them through soft iron or other magnetic metals. If you move a wire through these 'lines' a voltage is generated across the ends of the wire and this can be turned into an electric current by closing the loop of the wire.
yes,the direction of electric force on a charge is tangent of field lines.
Iron has a very high permeability. So it lets maximum number of Magnetic lines of force to pass through it. The closer is the ironic conductor to the magnet, more is the number of lines of force passing through the ironic object. That is why the magnet attracts the ironic object.
All I can really tell you is that one of the properties of a magnetic force is called flux. They are invisable lines that, when cut or "passed through" by a copper conductor will create a small voltage...That is how the alternator in your car works.
One represents a field of one kind, the other represents a different kind. true Answer 2 I wonder what you mean by an electric field. You may mean the magnetic field produced by an electromagnet as opposed to a permanent magnet. Well, they are both the same. Answer As far as electrical conductors are concerned, a magnetic field is produced by an electric current, whereas an electric field is produced by potential. The magnetic field… Read More
For conductors, the electric field perpendicular to its surface and no field exist within the conductor. As a result the equipotential lines are found near the surface. They are parallel to the surface since equipotential are perpendicular to field lines.
An electric field has what are called lines of force that radiate outward from the electric charge that creates them. It is the "touch" or the interaction with these lines of force that allow an electric field to exert a force (an electrostatic force) on anything with an electric charge. A fundamental law of electrostatics is that like charges repel and opposite charges attract. A charge will have an electric field around it, and if… Read More
An electric field has both magnitude and direction and can be represented by lines of force, or field lines, that start on positive charges and terminate on negative charges.
to calculate the force on a charged body
Current through a conductor forms a magnetic field. The "Right Hand Rule" will tell you the direction: Point the thumb of your right hand along the conductor in the direction of current flow (from negative to positive) and the fingers of the right hand curl in the direction of the magnetic field force lines.
Electric field lines or electric line of force is the path along which a small positive test charge would move if free to do so.
Electric flux provides that basis.
When magnetic flux lines of force are cut by induced voltage between magnetic and electric currents. Electromagnetic induction is created.
To reduce the electric field intensity at the surface of the conductor which can lead to corona discharge and insulation breakdown. By using bundled conductors, the electric field is distributed between the four (in the case of 400-kV lines) conductors, thus reducing the field intensity per conductor.
electrical lines of force come out from the positive electrical charge so as magnetic lines of force comes out from north magnetic pole.
It's not. The 'lines' indicate the direction of the field at each point in space, but they reveal nothing about the magnitude (strength) of the field.
Both are Inverse square law. It corresponds to the concept of lines of force spreading out uniformly from a source (mass or electric charge). If you imagine these line passing through a sphere surrounding the source at a distance R, The lines have to pass through its surface area of 4pi.R^2, so their density goes inversely as the square of the radius, (inverse square law) and hence the concept of lines of force.
There are several ways to produce a sinusoidal signal. It is the natural waveform produced by an alternator in which a conductor is rotated through a magnetic field. The constantly changing angle between the conductor and the magnetic lines of force produce the sinusoidal signal. A sinusoidal signal can also be produced electronically with an oscillator circuit.
Not at all. Glass doesn't conduct electricity. in fact they use glass as an insulator on electric lines.
Why are the equipotential lines near conductor surfaces parallel to the surface and why perpendicular to the insulator surface mapped?
Charged surfaces are linked by an electric field, which is represented by lines of force that are perpendicular to the charged surfaces. A voltage gradient exists along the direction of these lines of force. So, for each line of force, those points that exist at identical potentials can be linked to show lines of equipotential, and these lie at right angles to the lines of force. Lines of equipotential visually represent the voltage gradient within… Read More
There ARE no magnetic lines of force. The magnet and iron filings demonstration causes the illusion of lines, but if you take a picture of the "lines" and replace the paper and iron filings, the "lines" will appear in a different place. But if there WERE lines of force they probably could exist in vacuum.
The electric lines of force. A repelling force is between two like charges. An attractive force is between two opposite charges.
They are force field lines at right angles to each other as depicted in the related link.
The electric field intensity at a point is the force experienced by a one coulomb positive charge placed at that point. If suppose 5 C charge experiences a force of 20 N then 20/5 = 4 N/C will be the field intensity That could also be sensed as the number of electric (imaginary) lines of force crossing at right anles for unit area. Here no need to bring unit area. Just 0.0000001 sq m is… Read More
magnetic lines of force
Test charge, I think is the answer you are looking for.
Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge
The distinctions which are thought to exist between static electricity and current electricity are unfounded and , if subjected to a rational examination , patently absurd. Static electricity maybe described as an unequal distribution of charge (either excess positive or negative charge ) on a conductor , which results in an electrical force existing at right angles to the plane of the surface of the conductor. In a spherical conductor this results in the lines… Read More
