This resource is an animated movie, which combines voice over, text and images to explain what is meant by magnetic imaging. It explains how magnetic imaging can assist in mineral exploration by measuring the local magnetic field characteristics of a surveyed region. It describes how an analysis of aboveground magnetic fields can indicate the presence of underground ore deposits.

A short animation about magnetic imaging can be found on our YouTube channel, by clicking here.
