Magnetic solids can be demagnetized quickly with a short laser pulse, and there are already so-called HAMR (Heat Assisted Magnetic Recording) memories on the market that function according to this ...

Prolonged exposure to magnets can affect the functionality of your credit card. Cards with magnetic strips can also become demagnetized due to dirt, scratches and other damage. EMV chip technology has ...

It's a strange scientific phenomenon: ultra-thin magnets are solid, but when zapped with lasers, they actually behave like fluids. This fact has been known by academics for years. When an ultra-thin ...

Rare earth elements are used to produce magnets with very high strength that also strongly resist demagnetization, their performance is key to modern motors such as those in electric vehicles (EVs).

The use of permanent magnets is increasing in modern electrical machines because of the need for reduced size and higher performance. An important consideration in electrical machine design is the ...

A research team led by Prof. Sheng Zhigao from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with Prof. A.V. Kimel from Radboud University, has ...
