a. Use MathJax to format equations. The total number of turns of this inductor is 16. If the current is not changing over time, the flux is not changing in time, so no emf is induced. (3) The voltage across the inductor is related to the flux by the number of turns of the coil. Eq. It is actually worse than when I used to calculate turns using area and AL values back in about 1983. In accordance with Lenzs law, the negative sign in Equation \ref{14.10} indicates that the induced emf across an inductor always has a polarity that opposes the change in the current. the turns. This represents the smallest core size and maximum ALat which saturation will be avoided.
