Question

Q15. Assertion: Magnetic fields produced by current carrying circular coil are in form
of straight lines at the centre.
Reason: Magnetic field is non-uniform and parallel to the plane of the coil ​

Answer 1

Explanation:

Magnetic field due to current carrying wire can be comprehended by using magnetic filed lines which are concentric circles with centre at the axis of the conductor and its direction can be determined by Maxwell's right hand grip rule.

Thus the magnetic field is uniform and perpendicular to the plain of coil
