Abstract
The purpose of this study is to calculate the electric field produced by an implanted microcoil during magnetic stimulation of the brain. The electric field of a microcoil was calculated numerically. The maximum value of the induced electric field is approximately 0.000026 V/m for a 1 mA, 3 kHz current passed through the coil. This electric field value is too small to cause neural stimulation. Previous studies reporting magnetic stimulation using a microcoil must have been exciting neurons by some other mechanism.
