Answer:A
When a current-carrying coil is placed on a metal frame, something important happens:
As current flows through the coil, it creates a magnetic field.
This magnetic field changes (especially when current is switched on/off or varies).
The changing magnetic field induces an e.m.f. in the same coil — this is called back e.m.f..
👉 This phenomenon is known as Self-inductance.
