Assertion (A) : The magnetic field at the centre of the circular coil in the following figure is zero.
Reasen \( (R) \) : Since I1 \( =\mathrm{I} 2 \). Therefore the magnetic field due to one part balances that due to the other part of the circle.
(1) both Assertion and Reason are true and the Reason is correct explanation of the Assertion.
(2) both Assertion and Reason are true but Reason is not correct explanation of the Assertion.
(3) Assertion is true but the Reason is false.
(4) Assertion is false but Reason is true
