Nobelist achievement in physics.....TRP likes magnetism, not electricity so much but they meet

[Mark Kohut]

Although giant magnetoresistance does sound a bit like one of those mutants in the "X-Men" movie series, it actually describes a phenomenon at the junction of electricity and magnetism: When two layers of a metal such as iron are separated by a thin layer of another metal such as chromium, the application of a magnetic field can change the resistance of the structure - which determines how much electricity will flow through it.
