is practically immaterial whether the ampere-turns are distributed overthe whole circumference or are wound alltogether at one part, as shown in Fig. 59. Ineither case we can apply equation (43) on page61 and get B=lxH = 0-47r.j (48), where I apphes no longer to the length of thecoil, but to the… … 66 Electrical Engineering the lines, then the total number of lines or the total magnetic flux is givenby the equation t..o-4^.X.A 0 = 2^. (49). fi.A The denominator of the right-hand side of this equation has a similarform to the expression for electrical resistance in the equation ^ a The…
