The developed gradiometer achieved an impressive sensitivity of 4 fT/cm/ $\sqrt {\text {Hz}}$ using magnetic coils of various radii to simulate diverse sources. The experimental results indicate that ...

We’ve rounded up the best MagSafe, Qi2 and MagSafe-compatible magnetic chargers, from the plain pad to multi-functional stands (up to six devices charged), and even the most colorful—from snap ...

Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the ...
