$begingroup$ A current impulse (infinite di/dt) can only pass through a perfect inductor if the terminal voltage across the inductor is infinite. In a practical world, an inductor has self-capacitance and this means the impulse current bypasses the "magnetic" side of things and appears to pass through the inductor, but it doesn''t theoretically.

What is an electrical short circuit? How to handle it?
Normal Short Circuit: A normal short circuit occurs when a hot wire and a neutral wire, or two hot wires, come into direct contact. This bypasses the intended load and creates a low-resistance path, allowing a large amount of current to flow. Classic short circuits can be caused by damaged or deteriorated insulation, improper wiring connections, or faulty …

Why Do Capacitors Explode?
Internal Short Circuit . Physical harm or manufacturing flaws can cause the capacitor to short circuit. Capacitor short circuits allow large currents to pass through the shorted part due to the low resistance they create.
