Summary: Homo sapiens evolved a neurological system, a neuromuscular system, and a cardiovascular system that developed electromagnetic fields as part of their functioning. All of these could be impacted by magnetic fields. In addition, many proteins and physiologic processes utilize iron ions, which exhibit magnetic properties. Thus, complex organisms, such as humans, generate magnetic fields, contain significant quantities of iron ions, and respond to exogenous static and electromagnetic fields.

Summary: Weak magnetic feld and high voltage electrostatic feld-assisted refrigeration is a new physical method of food preservation, which not only does not contaminate food but also avoids adverse efects on the human body. The efect of spinach preservation under diferent magnetic feld strength and electric feld strength assisted refrigeration was investigated, with conventional refrigerator preservation being used as a control.
