A method is described for evaluating electric fields induced by ELF magnetic fields into electrically inhomogeneous, low‐conductivity (<5 S/m) structures. It is applied to cylinders and spheres, and numerical results are given for electrical properties that are representative of some tissues, or of cells embedded either in saline solution or a tissue matrix. Surface currents on spherical cell boundaries are estimated and compared with thermal noise due to ion motion.
