Finding current using in a loop

  1. Aug 7, 2010 #1
    NOT ASKING FOR ANSWER JUST EXPLANATION, IM REDOING THIS QUESTION FOR FINALS, I HAD PROBLEM WITH THIS BEFORE, BUT FORGOT TO NOTE DOWN WHY....


    1. The problem statement, all variables and given/known data

    2. Relevant equations

    its given in the problem

    3. The attempt at a solution

    well i have done this, and was looking over it and not sure why they multiply flux by:dI/dt

    can some one clear this up for me
    EDIT: is it b/c after doing that we get dI/dt = 100S/s. i think it is, just want to make sure b/c when i did it i use of 100A/s as--> (100A/s)t...t--> time and did it and got correct answer

    yeah you reasoning is correct. if you use I=100t when you derive you will get 100, which is same as 100A/s.
