Abstract Magnetic susceptibility measured by electromagnetic prospecting does not deliver equivalent information to that measured by magnetic prospecting. This originates from the natural remanent magnetization in magnetic anomalies and from differences in geometrical factors governing the responses of the features. This is illustrated by both theoretical and experimental results. Advantage can be taken by applying both methods simultaneously on magnetically favourable archaeological sites.
