Question

the diagram below shows the magnetic field lines of earth in a limited space of the lengths of parlour and what are the magnetic field lines uniform or nonuniform where is the position of geographical of a or b​

Answer 1

The magnetic field lines are uniform as these are equidistant. It is to be noted that the current flow will be in the same direction. The position of geographical is in a, which is north pole.

Explanation:

• It is to be understood that the magnetic field is one of the vector fields, which explains the electric charges magnetic influence in magnetized materials and in relative motion.
• The magnetic fields effects are usually observed in the permanent magnets.
• These repel or attract other magnets and pull on magnetic materials.
