Question, The effective length of a current loop may be shorter than the total length. Use only the single sided loops to plot "Lmeasured versus F". Can you determine the difference between effective and measured lengths from the intercept?

Requirement:

  • You must tell me the mathematical equation between effective and measured lengths from the y-intercept.
    1. (0.5): From Y = M X + By-intercept, write down the mathematical equation between Lmeasured and F entirely from all information of your GRAPH "Lmeasured versus F"

      ANSWER:

    2. (0.5): From the above result, revise it as Y - By-intercept = M X, then write down the physical meaning of Y - By-intercept.
