Below is an LC tank circuit and its V I plots:
I marked the points in red on the plots.
As far as I understand, at point a the capacitor is fully charged and the current is zero. At point b the current reaches to maximum and the voltage goes to zero(point y).
1-) Can we say that at point b, the net magnetic flux through the inductor is maximum?
2-) Here is my real confusion: According to Lenz's law the inductor should create a magnetic field which opposes the magnetic field rate through it. But in this case the magnetic field already is created by the coil it is not external. So does the Lenz law apply here? What can we say about the flux created by the current and the opposing magnetic flux?
Between the point a and b the current increases. Does that mean the net flux increases? What about the opposing flux? Is that in opposite direction?
