No, they do not exist. Electric field lines are only imaginary. They are the paths along which an imaginary unit charge would move when free. Their number is infinite as paths (Electric field lines) can be infinite.
Do field lines and electric fields actually exist?
Do field lines and electric fields actually exist? … electric fields do, but field lines do not. Field lines provide a model of an electric field but electric fields provide a method of calculating the force on a charged body.
Do the field lines actually exist?
4 Answers. The electric and magnetic fields are real things: they can store energy and transfer momentum. “Field lines” or “lines of force” are a visualization tool suitable for drawing vector fields. They are maps of the fields and the fields are real things.
Do electric field lines really exist what is about the field they represent?
Electric lines of force represents the direction of electric field. Electric lines of force can be defined as a way or path, it may be straight or curved, so that the tangent at any point to it gives the direction of the electric field intensity at that point.
Is it possible for an electric field to exist at some point in space at which there is no charge?
Q20 Is it possible for an electric field to exist at some point in space at which there is no charge? Yes, all we need to have is a charge somewhere in space that can exert a force on a positive test charge brought to that point in space.
Does an electric field exist in a vacuum?
1) YES, electric fields exist and can extend/propagate through a vacuum.
Are magnetic fields infinite?
A magnetic field has no sources or sinks (Gauss’s law for magnetism), so its field lines have no start or end: they can only form closed loops, extend to infinity in both directions, or continue indefinitely without ever crossing itself.
Can electric field lines cross?
Electric field lines never cross each other. Electric field lines are most dense around objects with the greatest amount of charge. At locations where electric field lines meet the surface of an object, the lines are perpendicular to the surface.
Can field lines end without a charge?
Electrical field lines can only begin and terminate at charges.
Are electric field lines straight?
Electric field lines are always straight. All electric potemtials are measured with respect to the negative terminal of the power supply.
Why do electric field lines never cross?
Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.
Can an electric field exist inside a conductor?
No electric field exists inside the conductor, since free charges in the conductor would continue moving in response to any field until it was neutralized.
