Littelfuse has created a three pin magnetic switch that draws only 200nA and operates at up to 50Hz. Called LF21112TMR, the detector uses a combination of TMR (tunnelling magneto-resistance) sensing ...

Near Earth's magnetic poles, some of Earth's magnetic field - shown as red in this diagram - loops out into space and connects back to Earth. But some of Earth's polar magnetic field connects directly ...

Earth’s magnetic field—which creates our planet’s north and south pole—is far from fixed. In fact, the field is quite active; sometimes it weakens, and even reverses, causing Earth’s polarity to ...

Earth spins, shifts, and now… flips? Our planet’s gymnastics routine continues underneath our feet nearly every day, but researchers at the Helmholtz Centre for Geosciences in Germany recently mapped ...
