Why is it necessary that the field lines from a point charge placed in the vicinity of a conductor must be normal to the surface of the conductor at every point?
Answers
Explanation:
As suggested by Marie Ampere, a current carrying conductor exerts a force when a magnet is placed in its vicinity. Similarly, a magnet also exerts equal and opposite force on the current carrying conductor. The direction of force over the conductor gets reversed with the change in direction of flow of electric current
Answer:
Field lines must be perpendicular to the surface and cannot be at any other angle.
Field lines near a conductor must thus be perpendicular to the conductor's surface.
Explanation:
Field lines must be perpendicular to the surface and cannot be at any other angle.
Field lines near a conductor must thus be perpendicular to the conductor's surface.
A conductor's surface is an equipotential surface.
Field lines are oriented from greater potential to lower potential, and the conductor's surface is an equipotential surface.
Field lines must thus be perpendicular to the surface and cannot be at any other angle.
Field lines near a conductor must thus be perpendicular to the conductor's surface.
According to Marie Ampere, a magnet positioned close to a current-carrying conductor causes it to exert a force. A magnet works in a similar way, applying an equal and opposing force.
