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 ...

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?

Japan’s NdFeB magnet demand, totaling 7,500 tons, reflects its tech-driven economy, with automotive, electronics, energy, and ...

Scientists have developed the world's strongest iron-based superconducting magnet using AI, in what could be a breakthrough for affordable MRI machines and the future of electrified transport.

Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium ...

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 ...

which has iron in it. Try the activity to see which metal objects are magnetic. Then try another fun activity with metals and magnets! Use tape to attach the magnet to the ruler so that the magnet is ...
