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.

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 ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

This can be "seen" in two dimensions if iron filings are sprinkled on a sheet ... as this helped to concentrate the 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.

and changes in free radical levels influence the magnetism of living tissues and how they respond to externally applied magnetic fields. These findings provide a deeper understanding of how iron ...

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. (Nanowerk News) A flower-shaped structure only a few ...

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the ...
