Please answer the following question: Process:  - Electromagnet creates magnetic field with electricity - Conductive copper wire is wrapped around a piece of metal - An electric current gets introduced from power source - Flows through the wire - Magnetic field gets created in the wire - And the metal gets magnetized - When turned off it is no longer magnetic.  suppose trapping more heat radiation happens, how will it affect a WEAKER electromagnet.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process
A:
not impacting any step of the process
