The Effect of Static Magnetic Field on Electrical Properties of Lens

We investigated the effect of a static magnetic field (0.1 T) on various electrical parameters of goat eye lens using a computer-aided AC impedance system (EG&G 278) at 30°C. Results of measurements on voltage-current characteristics showed that the static magnetic field alters the current flow in the tissue. The complex impedance plane drawn between real (Z') and imaginary (Z) parts in the form of a Cole-Cole plot demonstrates that under magnetic field, the distribution factor a decreases from 0.3 ± 0.006 to 0.24 ± 0.005 and the extracellular resistance (Re) increases from 52 ± 1.3 to 60 ± 1.5 K ohms in the lens tissue. An attempt has been made to explain the interactive behavior of the magnetic field with the electrical changes in the lens.
