Question

Assertion(A) : For a point on the axis of a circular coil carrying current ,magnetic field is maximum at

the centre of the coil

Reason(R) : Magnetic field is inversely proportional to the distance from the circular coil

a) Both (A) and (R) are true and (R) is the correct explanation of (A)

b) Both (A) and (R) are true and (R) is not the correct explanation of (A)

c) (A) is true and (R) is false d) (A) is false and (R) is true
​

Answer 1

Answer:

option B is the answer.....

Answer 2

a) Both (A) and (R) are true and (R) is the correct explanation of (A)

• At the centre of the current-carrying circular coil, the magnetic field is strongest. The magnetic field lines of force generated by the circular current coil are perpendicular to the plane of the circular loop and create concentric circles around the conductor's perimeter.
• The magnetic field is inversely proportional to the distance from the circular coil. This is the reason why the magnetic field is stronger at the centre.
