Electric field induced in cells in the human body when this is exposed to low-frequency electric fields

A detailed analysis is carried out of the electric field induced in a cell when the body is exposed to an incident axial electric field at 50--60 Hz. It is shown that the field in a spherical cell is effectively shielded by the membrane so that the induced field in its interior is negligibly small. It is also shown that the induced electric field in a cylindrical cell (which is long compared to its radius) is the same as the axial field outside the cell. In this case, the cell membrane has no shielding effect.
