    12-10-25 ESA's quartet of satellites studying Earth's magnetosphere(磁气圈) , Cluster, has discovered that our protective magnetic bubble lets the solar wind in under a wider range of conditions than previously believed. Earth's magnetic field is our plane...

  • 隐形磁场成为现实

    12-03-23 Universitat Autonoma de Barcelona researchers, in collaboration with an experimental group from the Academy of Sciences of Slovakia, have created a cylinder which hides contents and makes them invisible to magnetic fields. The device was built using...

  • 热量也可以记录信息

    12-02-08 An international team of scientists has demonstrated a revolutionary new way of magnetic recording which will allow information to be processed hundreds of times faster than by current hard drive technology. The researchers found they could record i...

  • 脑部磁刺激可治疗某些中风病人

    11-12-15 Imagine waking up and being unable to see or recognize anything on the left side of your body. This condition, called hemispatial neglect, is common after a stroke that occurs on the right side of the brain. The current treatment of attention and co...

  • 美国建成世界最强脉冲磁场

    11-08-24 Researchers at the National High Magnetic Field Laboratory's Pulsed Field Facility at Los Alamos National Laboratory have set a new world record for the strongest magnetic field produced by a nondestructive magnet. The scientists achieved a field of...

    11-06-29 Rossendorf set a new world record for magnetic fields with 91.4 teslas. To reach this record, Sergei Zherlitsyn and his colleagues at the High Magnetic Field Laboratory Dresden (HLD) developed a coil(线圈) weighing about 200 kilograms in which ele...

  • 人类确实有第六感

    11-06-25 It has long been known as ESP, Spider Sense, or the ability to see things before they happen. But now scientists have proved that humans really do have a sixth sense - that lets them detect magnetic fields. 一直以来,第六感也被称为超感知觉、蜘蛛感应...

  • 人类能感知地球磁场吗?

    11-06-22 For migratory birds and sea turtles, the ability to sense the Earth's magnetic field is crucial to navigating the long-distance voyages these animals undertake during migration. Humans, however, are widely assumed not to have an innate(先天的) mag...
