A circular current-carrying coil has a radius `R`. The distance from the centre of the coil, on the axis, where `B` will be `1//8` of its value at the centre of the coil is

A circular current carrying coil has a radius R. The distance from the centre of the coil on the axis where the magnetic induction will be (1//8)^(th) of its value at the centre of the coil is,

A circular current carrying coil has a radius R. The distance from the centre of the coil on the axis where the magnetic induction will be (1)/(8) th to its value at the centre of the coil, is

A circular current carrying coil has a radius R. The distance from the centre of the coil on the axis where the magnetic induction will be (1)/(8) th to its value at the centre of the coil, is

A circular current carrying coil has a radius a. Find the distance from the centre of coil, on its axis, where is the magnetic induction will be 1/6th of its value at the centre of coil.

An electric current is flowing in a circular coil of radius r .If at a distance sqrt(K)r from the centre on the axis of the coil the magnetic fleld be (1)/(8) th of it's value at the centre,then find the value of K.

The radius of a circular current carrying coil is R. The distance on the axis from the centre of the coil where the intensity of magnetic field is (1)/(2sqrt(2)) times that at the centre, will be:
