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

If you need help visualizing magnetic fields, these slow-motion video captures should educate or captivate you. Flux lines are difficult to describe in words, because magnet shape and strength ...

Iron is magnetically soft – it can be easily magnetised and demagnetised. Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic ...

Reader Jayant Bhalerao, a college physics instructor, found the story useful in class: “We will share it with our students, so that they can appreciate how ...

The magnetic field is shown by lines with arrows that point from north to south. You can tell how old some coins are by testing them with a magnet. 5p and 10p coins made before January 2012 are ...

the angle at which magnetic field lines intersect the Earth. The turtles use these two pieces of information, which vary at every point on the planet's surface, as navigational markers that help ...

As the time line at right shows ... Moreover, while a severe weakening or disappearance of the magnetic field would lay us open to harmful radiation from the sun, there's little evidence to ...

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 ...
