Question

Draw the electric lines of force to represent a non uniform electric field,

increases from downward to upward direction in the plane of paper.​

Answer 1

Non-uniform magnetic lines:

Explanation:

When a magnetic field in a certain region is of same direction and constant magnitude, we call it uniform magnetic field. The lines of uniform magnetic field are called uniform magnetic lines.

Contrary to that, when the direction of the magnetic field or its magnitude or both varies within the given region, then it is known as non-uniform magnetic field. The lines of non-uniform magnetic field are called non-uniform magnetic lines.

Please refer to the attached picture for the diagram.
