Dynamo in a Box Dan Lathrop is building a planet in his lab. If everything goes as planned, his 3-meter-tall metal sphere will self-start its very own dynamo, a process where heat and motion establish a magnetic field.   |

Magnesium oxide might be liquid in super-Earths There may be more planets outside our solar system with protective magnetic fields than previously thought. That's the implication of a US study, which has demonstrated that the common planetary mineral magnesium oxide turns into a metallic liquid at high pressure. |

Microscopic mix strengthens magnet Magnets are usually an either-or proposition. They either generate a strong magnetic field or they hold up well in the presence of external magnetic fields. A method that mixes the two types of magnets at the nanoscale could pave the way for smaller electric motors and generators. |

That's one scenario suggested by a recent investigation of a venerable equation that serves as a model for planetary tidal effects. |
