Can two electric field lines intersect each other?
Electric lines of force never intersect because, at the point of intersection, two tangents can be drawn to the two lines of force. This means two directions of the electric field at the point of intersection, which is not possible.
Why can’t two field lines intersect each other?
Reason – The two magnetic field lines do not intersect each other because if they do, it means at the point of intersecting, the compass needle is showing two different directions, which are not possible.
Why are electric field lines not closed loops?
The electrostatic field lines do not form closed loop because no electric field line exist inside the charged body.
Why magnetic field lines called closed curves?
Magnetic field lines are closed curves as they propagate from the North pole outside the magnet’s body to the magnet’s body and from the south pole to the north pole inside the magnet’s body. Hence, the magnetic field lines are closed.
What are the two properties of magnetic field lines?
Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows:
- The field is tangent to the magnetic field line.
- Field strength is proportional to the line density.
- Field lines cannot cross.
- Field lines are continuous loops.
Why do electric lines of force never intersect each other can two equipotential surface intersect?
They can’t intersect each other because two different equipotential surface have different electric potential, so if they intersect then the point point of intersection will have two different potential at the same point which is not possible.
Is it possible that electric potential at a point is zero but not electric field?
Yes, electric potential can be zero at a point even when the electric field is not zero at that point. At the midpoint of the charges of the electric dipole, the electric field due to the charges is non zero, but the electric potential is zero.
