Decay of the electric with distance from various TMS coils. Phantom measurements of the electric field induced at each distance is calculated relative to the field induced 1 cm from the coil, in the ‘z’ (superior-inferior) direction. Data are presented for the H1-coil, H2-coil, double cone coil and figure-8 coil.
