Two infinitely long straight wires lie in the xy-plane along the lines x = ±R. The wire located at x = +R
carries a constant current I1 and the wire located at x = –R carries a constant current I2. A circular loop of radius R is suspended with its centre at (0, 0, √3R ) and in a plane parallel to the xy-plane. This loop carries a constant current I in the clockwise direction as seen from above the loop. The current in the wire is taken to be positive if it is in the + ˆj direction. Which of the following statements regarding the magnetic field  is (are) true?
  • a)
    If I1 = I2 , then  cannot be equal to zero at the origin (0, 0, 0)
  • b)
    If I1 > 0, and I2 < 0, then   can be equal to zero at the origin (0, 0, 0)
  • c)
    If I1 < 0, and I2 > 0, then  can be equal to zero at the origin (0, 0, 0)
  • d)
    If I1 = I2 , then the z-component of the magnetic field at the centre of the loop is 
Correct answer is option 'A,B,D'. Can you explain this answer?
Verified Answer
Two infinitely long straight wires lie in the xy-plane along the lines...

(A) If I1 = I2, magnetic field due to infinite wires is equal to zero . So there must be a non–zero magnetic field at O due to the current carrying loop.
(B) If I1 > 0 & I2 < 0 , magnetic field due to straight lines are along positive z–axis and due to loop it
is along negative z–axis.
(C) If I1 < 0 & I2 > 0 magnetic field due to straight wires are along negative z–axis and due to the loop it is also along negative z–axis.
(D)
