The field normal to the plane of a wire ...

The field normal to the plane of a wire of `n` turns and radis `r` which carriers `i` is measured on the axis of the coil at a small distance `h` from the centre of the coil. This is smaller than the field at the centre by the fraction.

A

`(3)/(2)(h^(2))/(r^(2))`

B

`(2)/(3)(h^(2))/(r^(2))`

C

`(3)/(2)(r^(2))/(h^(2))`

D
