Pioneering tomography provides clearer snapshots of the Earth's changing magnetism
The Earth's magnetic field forms a protective bubble that shields the Earth from radiation streaming from the Sun. Over the years, changes in the Earth's magnetic field have been recorded by iron-rich minerals affected by magnetic influences. When the minerals become trapped in place, they are like snapshots in time of the Earth's changing magnetic field. However, the 'snapshots' can be out of focus when small amounts of minerals that are not good recorders are present. Using pioneering non-destructive micro-magnetic tomography, MIMATOM plans to zoom in on individual minerals rather than the bulk, thus providing a clearer picture of magnetic field changes over time. Insight will enable us to more accurately predict the future of our magnetic bubble.
