Problem 28.4: Amperian loop and path integral for uniform field

Please wait for the animation to completely load.

  1. Find ∫ B · dl for each side of the square wire (position is given in millimeters and the magnetic field strength is given in millitesla, 10-3 T).
  2. What is the total value of the path integral ∫ B · dl for the field shown? Explain.

Restart.
