Abstract
When designing an in-line metal detector, a three coil axially symmetric design is often employed. For maximum sensitivity to small particles, the spacing of the coils is an important factor. A formula is derived which predicts the signal produced by a metal sphere when moved along the axis of such a detector and from this a graph is produced to determine the optimum coil spacing.
