A scientist wants to study the in-plane spiral tubes used in chemical reactors. To
proceed with his study, he took a thin insulated wire and converted it into a plane
spiral of 140 closely wounded turns. The required field at the centre of the spiral is
8.8 µT and the current flowing across the spiral is 10 mA. In the given figure, the
radius of the inner turns is a and the radius of the outer turns is b. If b is twice of a
then find the inner and outer radii to conduct the experiment.
