and it may soon be possible to build permanent magnets as strong as neodymium magnets, but without any rare earth metals. In fact, the only thing needed to make them is iron and nitrogen ...
Even today, it remains the most powerful permanent magnet in the world. The two researchers — Japanese engineer Masato Sagawa and American metallurgist John Croat — have been awarded the 44th ...
Welcome a magnetar. A magnetar (a type of neutron star) has a magnetic field as strong as 10¹⁴-10¹⁵ Gauss, making it the most magnetic object (known) in the Universe. To put things into perspective, ...
A top scientist has invented super strong magnetic grippers. These allow a man to climb the outside of a steel tower. The magnetic grippers were funded by the military, who wanted to be able to ...
