It can be, and normally the heat dissipates, but not when it curled tightly. So we get small scale heat soak if its coiled up tightly.
>>Is that the same as induction?
When you have the cable coiled up, you generate an EMF, the EMF screws with the resistance/inductance of the cable (more so with impure copper cables) increasing the heat generated
Add that to the heat soak and ...........
