To better protect kids, the CPSC in 2022 set strict rules on the size and strength of loose magnets. The agency banned small ...

In a first-of-its-kind test, scientists used a levitated magnet to search for dark matter, the unidentified substance believed to be present throughout the cosmos. If dark matter is made up of ...

"If magnets are accessible to children, some children will inevitably ingest them, leading to a wide range of severe ...

The creation of magnets involves a fascinating process that blends science and precision. It all begins with raw materials ...

THE observation of magnetic fields set up by electric currents induced in ocean swell by its movement through the Earth's magnetic field has recently been reported 1. The observations were made in ...

Magnetic field therapy uses different kinds of magnets on the body to help boost your overall health. It may also help treat certain conditions. Electrically charged magnetic therapy ...

Abstract: In this paper, an axial-field flux-modulated (AFFM) machine with multiple permanent-magnet (PM) excitations for electric ... Then, taking axial-field magnetic gears with a gear ratio of 19/5 ...

Their approach is to sense anomalies in the Earth’s magnetic field and compare them with a known map of the field to work out their position. And because they use quantum sensors for this process, ...

Abstract: This article presents a fast algorithm for calculating the air-gap magnetic field and force of a multishaft ring-plate magnet gear (MRMG). The magnetic field and force are divided into ...

New research reveals how dramatically Earth’s magnetic field weakened and shifted during an event called the Laschamps geomagnetic excursion, potentially influencing human evolution at a pivotal ...

Scientists have long puzzled over why Mars, once protected by a global magnetic field like Earth, now shows only a magnetic imprint mostly concentrated in the planet’s southern hemisphere. A new study ...
