If a finite length of wire having a total length QR = 80 m, a current of 10 A is flowing in it.
A point P from the origin point or reference point is away at a distance of 4 mm. If the point P is making an angle of 75° with the point Q in clockwise direction & 60° with the point R in anticlockwise direction. What will be the magnetic field density B, at point P.
  • a)
    1.68 m-Wb/m2
  • b)
    1.12 m-Wb/m2
  • c)
    0.682 m-Wb/m2
  • d)
    0.458 m-Wb/m2
Correct answer is option 'D'. Can you explain this answer?

As we know that due to a finite length of wire in which I current is flowing, at a point P where the point P makes angle θ1 with point θ in clockwise direction &θ2 with R in anticlockwise direction is calculated as-
B =
where the sign of angle is tve, is being taken, a is the distance from a reference point.
S0 B at point P
B =
= 2.5 x 10-4(0.966 + 0.866)
= 0.458 x 10-3Wb/m2
B = 0.458 m-Wb/m2
