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.  Perturbation hypothesis: suppose volcanoes become inactive happens, how will it affect a WEAKER electromagnet.  Does the supposed perturbation have an effect (direct or indirect) on the process?

no
