An ideal LC circuit consists of an inductor with self-inductance \(L\) connected across an initially charged capacitor of capacitance \(C\). The circuit undergoes undamped electromagnetic oscillations with angular frequency \(\omega = \dfrac{1}{\sqrt{LC}}\). At the instant the electric current flowing through the inductor reaches its maximum magnitude, the charge on the capacitor is zero and the potential difference across the inductor is zero. Which of the following best explains why the potential difference across the inductor is zero at this instant?
