The figure shown the cross section of a long cylindrical conductor through which an axial hole of radius `r` is drilled with its centre at point `A`. `O` is the centre of the conductor.
If the identical hole were to be drilled centred at point `B` while maintaining the same current density the magnitude of magnetic field at `O`

A

will increase

B

will decrease

C

will remains the same

D

May increase of decrease depending on the value of `r`.

Text Solution
