This allowed the team to detect and measure the unseen magnetic field lines, much the same way iron filings can reveal the magnetic field around a magnet. The team thinks that the measured three ...

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

Magnets are also surrounded by a similar three-dimensional field. This can be "seen" in two dimensions if iron filings ... The filings align themselves along the lines of magnetic force ...

Scientists have developed a tiny flower-shaped structure that’s made of a nickel-iron alloy to concentrate and locally ...

Magnetotactic bacteria synthesize magnetic iron nanominerals ... the bacteria to passively align with Earth's geomagnetic field lines in both the Northern and Southern Hemispheres.
