Explanation / Answer

here,

d1 = 0.134 m

I1 = 16.5 A , I2 = 7 A

d2 = 0.128 m

the magnitude of the magnetic feild at point P located a distance d2 , B = u0 * I1 /( 2 * pi * (d1 + d2)) + u0 * I2 /( 2 * pi * d2)

B = 1.26 * 10^-6 /( 2 * pi ) * ( 16.5/(0.134 + 0.128) + 7/(0.128)) T

B = 2.36 * 10^-5 T

the magnitude of the magnetic feild at point P located a distance d2 is 2.36 * 10^-5 T

using right hand thumb rule

the direction of feild is INTO THE Plane of paper
