Magnetic Field Produced by Straight Currents Video Lessons

Concept

# Problem: A long, straight wire lies along the y-axis and carries a current 8.00 A in the -y-direction (Figure 1). In addition to the magnetic field due to the current in the wire, a uniform magnetic field Bapp with magnitude 1.50×10−6 T is in the +x-direction.What is the magnitude of the total field at the point x = 0, z = 1.00 m in the xz-plane?
