Question
A long straight very thin wire on the y-axis carries a 10-A current in the positive y-direction. A
circular loop 0.50 m in radius, also of very thin wire and lying in the yz-plane, carries a 9.0-A
current, as shown. Point P is on the positive x-axis, at a distance of 0.50 m from the center of the
loop. What is the magnetic field vector at point P due to these two currents? (μ0 = pi × 10-7 T ·
m/A)
15)
A) zero
B) ^ -8.0 × 10-6 T k
C) ^ ^ (+4.0 × 10-6 T) i - (4.0 × 10-6 T) k
D) ^ ^ (-4.0 × 10-6 T) i - (4.0 × 10-6 T) k
E) ^ ^ (-4.0 × 10-6 T) i - (8.0 × 10-6 T) k
