In fact, the only thing needed to make them is iron and nitrogen, plus an understanding of crystal structure and some engineering ingenuity. To start things off, what even is a permanent magnet?

A research team led by Prof. Zhang Xin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has ...

Begin by melting a small amount of solder on the iron, then push the tip of the magnet wire a small distance into the molten solder and hold it there for a few moments. The enamel will bubble away ...

In 1982, two researchers working independently of each other developed the neodymium–iron–boron magnet, which was stronger than any known magnet. It revolutionized the low-cost mass production ...

How do magnets work? Discover the science behind magnetism, from electron movement to magnetic domains, and learn how magnets ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...

Magnetotactic bacteria synthesize magnetic iron nanominerals, which function as tiny compasses that allow the microbes to navigate using Earth's geomagnetic field. Earth's iron cycle is a very ...
