"Force submitted to a membrane is determined by the equation F=B*l*i, where B is the magnetic field within the voice coil, l the length of the coil and i the current". But I can tell you that for ...

Electric charges, Conservation of charge, Coulomb's law-force between two- point charges, forces between multiple charges; superposition principle and continuous charge distribution. Electric ...

Focal Utopia Main 112 and 212 studio monitors have landed UM 112 is a three-way monitor; UM 212 is a 3.5-way design This is a high-end audio brand, and Utopia Main's pricing reflects that French audio ...

One to compute the magnetic field, which is the A-formulation equation, and one to compute the current density ... The system is composed of a transformer with a common copper primary coil and the HTS ...

Second, a formula is derived to quantify SNR, and a high SNR of 115 for the Larmor signal is observed after multiple optimizations. Finally, the experiment was carried out in the natural magnetic ...

Loggerhead turtles “dance” when exposed to food-associated magnetic fields, and their magnetic map may help them return to specific areas after long migrations.

Researchers at CU Boulder have created a new type of magnetic field sensor using atoms, offering increased precision.

Earth's magnetic field occasionally bursts into song — but these compositions are written with electromagnetic radiation, not sound waves. When converted to audio signals, though, these strange ...

“The current behaviour of magnetic north is something that we have never observed before,” William Brown, a global geomagnetic field modeler at the British Geological Survey, said in a statemen ...

the magnetic north pole of the planet is decided by Earth's magnetic field, which is constantly moving and never static. Scientists noted that over the past few years, the movement of the magnetic ...
