Abstract :
Magnetically induced current density has been measured in different concentrations of saline solution and in the cerebral cortex of cats in vivo. The results show that the current density decreases with distance from the stimulating coil and with increasing resistivity. The presence of the cranium attenuates the current density in the cortical tissue. The studies show that it is possible to measure directly current densities induced by magnetic fields
