Question

A neutral point is obtained at the center of a vertical circular coil

Answer 1

Answer:

neutral point is obtained at the centre of a vertical circular coil carrying current. The angle between the plane of the coil and the magnetic meridian is

Answer 2

Answer:

90 degrees

Explanation:

Magnetic meridian is a vertical N−S plane, the earth's magnetic field (Bh) lies in it.

To obtain neutral point at the centre of coil, magnetic field due to current (B) and (Bh) should be perpendicular to each other.
