2. Two wire loops of radius R=5cm are 20cm apart and concentric about a common axis. Each coil carries l=3 A that runs counterclockwise as viewed from the right in the picture below (which has a distorted aspect ratio). The eld anywhere along the axis of a current loop at distance 2 from the loop is ZKRZI Look at figure 19.28 in the text to find the direction. B=k' cm Text 20cm A. What is the magnitude and direction of the magnetic field on the axis and halfway between the loops (marked in the gure above)? Viola Helmholtz coils! B. What is the magnitude and direction of the magnetic field on the axis and halfway between the loops if the right-hand loop current is reversed and moves in a clockwise direction
