The magnetic field of two equal halfs of the loop is equal and opposite and so vecB=0.

Q.
Statement I: Figure shows a current carrying circular loop. The magnetic field at the centre of loop is zero.
Statement II: Magnitude of magnetic field at the centre of circular loop carrying current $i$ is given by $B = \frac{μ _{0} ni}{R}$ .

Both statement I and II are correct.

Both statement I and II are incorrect.

Statement I is correct but statement II is incorrect.

Statement II is correct but statement I is incorrect.

The magnetic field of two equal halfs of the loop is equal and opposite and so $B = 0$ .

Q. Statement I: Figure shows a current carrying circular loop. The magnetic field at the centre of loop is zero. Statement II: Magnitude of magnetic field at the centre of circular loop carrying current i is given by B=Rμ0​ni​.
