Learn how microphones and amplifiers work together to convert sound to electrical signals for clear audio output.

Abstract: Persistent current mode (PCM) is an ideal operation mode for high temperature superconducting (HTS) magnets with static magnetic fields. However ... of HTS magnets stacked by gourd-shape HTS ...

Mars' dramatic north-south divide has puzzled scientists for half a century. However, they may now have a conclusive answer.

Firstly, the structure and operating principle of the multi-shaped magnet rotor are presented. And the magnetic field and average torque of the MMR design are formulated mathematically through field ...

A new trick for illuminating the internal ordering within a special type of magnet could help engineers build better ...

Earth’s magnetic field is detected by species across the animal kingdom, but new research suggests that sea turtles may be ...

A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The compelling 2021 study tells the ...

Earth's magnetic field dramatically flipped a little more than 40,000 years ago. We can now experience this epic upheaval, ...

“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 ...

Dancing turtles show how animals use magnetic field as a map Dancing turtles have proved for the first time that some animals use Earth's magnetic field to create a personal map of their favourite ...
