Here's your first problem; connecting an inductor (a pure inductor) to a current source requires that to instantly drive the current, an infinite voltage must be present and things fall apart whe... | Qualitatively, anything that tries to reduce the current in the inductor is also trying to collapse the magnetic field in the inductor.

===================
If you want to animate the angle of a solid color filled pie segment like the one in your question, then you can do it by animating the `strokeEnd` of a `CAShapeLayer`.
The "trick" here is to make a very wide line. More specifically, you can create a path that is just an arc (... | So at last I have found a solution. It took me time to understand that there is **indeed no way to animate the fill** of the shape, but we can trick CA engine by creating a filled circle by making the *stroke* (i.e. the border of the arc) extremely wide, so that it fills the whole circle!
