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 ...

As a mom and a journalist who follows the toy market, I count magnetic toys among the least ... "Since the magnets help keep structures together, kids are able to build higher and wider," says ...

But they suffer from a fundamental drawback — to image individual atoms, samples have to be placed in strong magnetic fields. This makes it impossible to image materials that are strongly ...

Some of the most sensitive methods of measuring magnetic fields use interactions of resonant light with atomic vapour. Recent developments in this vibrant field have led to improvements in ...

[Peter] is currently working on a new version of his pocket-sized science tricorder, and he figured visualizing magnetic fields would be cool. This led to what can only be described as a camera ...

New results from China’s Chang’e 5 mission suggest that the Moon possessed a magnetic field well into its midlife, much longer than previously documented. In work published Jan. 1 in Science ...

As well as a few temporary reversals, the Earth's magnetic field – just like the Sun – can flip over long timescales. During the Brunhes–Matuyama reversal, the magnetic north could have been ...

By studying robins, scientists have found clues to how birds sense the Earth's magnetic field. Just as you might reach for a magnetic compass to find which way is north or south, birds are thought ...
