362575 A tightly wound 100 turns coil of radius \(10\,cm\) carries a current of \(7\,A\). The magnitude of the magnetic field at the centre of the coil is (Take permeability of free space as \({4 \pi \times 10^{-7} S I}\) units):

362576 Assertion :
The magnetic field intensity at the centre of a circular coil carrying current changes, if the current through the coil is doubled.
Reason :
The magnetic field intensity does not depend on radius of coil.
