Magnetic devices are components for creating, manipulating or detecting magnetic fields. This can include magnetic memories, magnetometers and devices for magneto-optics. Magnetism can also play a ...

Contrary to previous assumptions, the Moon's passage through Earth's magnetic field, or "geotail," does not lead to lower plasma densities. Listen to Story Scientists from the Space Physics Laboratory ...

The sensor is based on a time-harmonic magnetic field and has the advantage of strong detection ability for nonferromagnetic particles. The sensing mechanism of metal particles is the foundation for ...
