How Do Magnetic Fields Affect Cells? Like "at 100T, your body would _____ because _____ and at 1000T, your body would _____ because _____" and so on. Magnetic fields of the human body Developments in ways to measure the extremely weak magnetic fields emanating from organs such as the heart, brain and lungs are leading to important new methods for diagnosing abnormal conditions. However, it must be considered that there exists a potential physiological effect due to the magnetic properties of iron, found primarily in hemoglobin, but also known to accumulate in sinus bones. What is the maximum magnetic field that a human body can withstand? On May 23, 1956, a research center and observatory opened at Corbin, Va. to continuously monitor the Earth's magnetic field. Kanakov and co have worked out how this effect might play out in the human body; after all the body is filled with calcium ions in a fluid . Theoretically, this is the utmost effect of a magnetic field on human body.
