Nutation reducers have recently attracted increasing attention, as they are used in important components of industrial robot joints. A novel disk-type nutation magnetic drive (NMD), based on the ...

Calculations and analysis show that the primary contribution to the field generated by a magnetic dipole with arbitrary orientation comes from the source projection parallel to the geomagnetic field.

In an Earth-sized take on the age-old ‘correlation or causality’ question, researchers have come across a fascinating match between Earth’s magnetic field and its oxygen levels si… ...
