A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

Magnetic flux leakage (MFL) testing is a widely established non‐destructive evaluation technique used to assess the integrity of ferromagnetic materials in applications such as pipeline inspection and ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

In a recently published article in IEEE Electron Devices Magazine the authors, I was one of them, looked at the impact of external magnetic fields on spin tunnel torque magnetic random-access memories ...

A magnetic cloak works by diverting external magnetic fields so that, to an external observer, the object appears to be absent or invisible. Although this idea ...
