From the definition of tensor gradient and the definition of the magnetic field at any point (x, y, z) in Eq. 15, the gradient tensor G of the magnetic dipole field is given by the following equation.

"The discovery doesn't rule out the existing theory, because the expected magnetic field gradients could still be present, but it means that scientists need to take a closer look," wrote Cambridge ...

Birds don’t just follow landmarks or the stars—they might actually see Earth’s magnetic field. Scientists have uncovered a surprising quantum secret hidden in their eyes.

A critical procedure in diagnosing atrial fibrillation is the creation of electro-anatomic activation maps. Current methods generate these mappings from interpolation using a few sparse data points ...

Wow, they have done it again! While Garmin has always been at the top of the pile when it comes to GPS sports watches, there has been a lot more competition recently from the likes of Suunto, Coros, ...
