What is bx00 the x-component of the magnetic field produced

Question

Three infinite straight wires are fixed in place and aligned parallel to the z-axis as shown. The wire at (x,y) = (-14 cm, 0) carries current I₁ = 3.3 A in the negative z-direction. The wire at (x,y) = (14 cm, 0) carries current I₂ = 1.4 A in the positive z-direction. The wire at (x,y) = (0, 24.2 cm) carries current I₃ = 5.1 A in the positive z-direction.

1) What is B_x(0,0), the x-component of the magnetic field produced by these three wires at the origin?

2) What is B_y(0,0), the y-component of the magnetic field produced by these three wires at the origin?

3) What is F_x(1), the x-component of the force exerted on a one meter length of the wire carrying current I₁?

4) What is F_y(1), the y-component of the force exerted on a one meter length of the wire carrying current I₁?

5) What is F_x(2), the x-component of the force exerted on a one meter length of the wire carrying current I₂?
