This is exploited in popular demonstrations where the magnetic field of a bar magnet can be made visible. Small filings of iron are first scattered on the surface of a table and then a magnet is ...

Although we cannot see magnetic field lines, we can detect them using iron filings. The tiny pieces of iron line up in a magnetic field.

The iron filings in the image become induced magnets when they are near the bar magnet. They lose most or all of their magnetism when they are removed from the magnetic field.

Room-temperature magnetic and electronic traits make phosphorene nanoribbons promising for next-gen, energy-efficient nanoelectronics.

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...
