Problem

Three long, straight conductors X, Y and Z carry steady currents of

I_X = 4\,\text{A}

I_Y = 6\,\text{A}

and

I_Z = 3\,\text{A}

respectively. The perpendicular distances of three observation points from the conductors are: Point A is

2\,\text{cm}

from X, Point B is

4\,\text{cm}

from Y, and Point C is

1\,\text{cm}

from Z. a. (i) Arrange Points A, B and C in descending order of magnetic field magnitude. b. (ii) Support your answer with suitable ratio calculations.
