Why Do Field Lines Never Cross?
Field lines refer to the electric field lines which is actually invisible but existing. This concept was introduced by Michael Faraday. He conceptualized that there are pattern of lines emitted by the electric field. If an object is charged, then the space surrounding that objects is affected, thereby may create an electrified web of space. The field also makes use of a certain force on objects which are electrically charged.
In reality, there are no field lines but it was conceptualized to visualize the field and to understand how the magnetic fields work together. If these lines are visible then, these will not cross because there are forces that affect the forces of one another. This means that the electric field lines are opposing from each other. The lines in the filed may not be seen by the naked eye but the forces do exist. The lines do not interfere with each other and will never interfere with each other.
Field lines also carry with them the same charge. They always start from positive and end with a negative charge. In physics, opposite charges attract. In the case of field lines, they have the same charges so they could never attract one another. They will always repel no matter what the circumstances are.
Electric field lines are an imaginary line where the positively charged object moves towards the negatively charged. Because of these, electric field diagrams always have the features of being perpendicular to the surface where the object which is charged met. Field lines never intersect each other that’s why they never cross.
It’s impossible for 2 field lines to intersect or cross because if they do that means there were two directions of electric fields at the same point. In reality, there never was a time when electric fields go to different directions. Though imaginary, these lines follow the same pattern and that pattern will never allow them to cross.
