Can electric field make closed loops?

Posted on August 16, 2022 by Author

Can electric field make closed loops?

If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative. Therefore, we say electrostatic field lines never form closed loops.

Why does induced electric field form closed loops?

The electric field only has nonzero divergence when there is nonzero charge density. When charge density vanishes everywhere and there are only induced electric fields, the electric field is divergence-free like the magnetic field, and its field lines form closed loops like those of the magnetic field.

Do all magnetic field lines form closed loops?

Magnetic field-lines form closed loops which never begin or end. Thus, magnetic field-lines behave in a quite different manner to electric field-lines, which begin on positive charges, end on negative charges, and never form closed loops.

Why magnetic field form closed loops?

Magnetic lines are imaginary lines. Within the magnet, they move from south pole to north pole and outside the magnet they move from north pole to south pole. Hence, magnetic lines form continuous closed loops.

Do electrostatic field lines form electrostatic closed loops give reason?

The electrostatic field lines do not form closed loop because no electric field line exist inside the charged body.

Can electric field be Nonconservative?

Specifically, the induced electric field is nonconservative because it does net work in moving a charge over a closed path, whereas the electrostatic field is conservative and does no net work over a closed path. Hence, electric potential can be associated with the electrostatic field, but not with the induced field.

Why do magnetic fields form closed loops?

i Magnetic lines of force form continuous closed loops because a magnet is always a dipole and as a result the net magnetic flux of a magnet is always zero. ii When a diamagnetic substance is placed in an external magnetic field a feeble magnetism is induced in opposite direction.

Why do field lines surrounding a magnet always form closed loops?

So there is no source or a sink for magnetic field lines. The net flux of the magnetic field through any closed surface is zero. All the field lines that enter through the surface into a volume enclosed by the surface also exit through the surface. Hence Magnetic field lines always are closed loops.

Are electric field lines closed curves?

Electric field lines are open curves which originate from positive charge and terminate into negative charge.

Can field lines cross each other?

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.

Why do electric field lines do not cross each other?

The direction of electric field line generally changes from point to point and hence are curved lines. And this implies two directions of electric field intensity at the point of intersection, which is not possible. Hence, two field lines never cross each other.
