Earth’s magnetic field is essential to life on our planet. It protects Earth from cosmic radiation and acts as a shield ...

An all-superconducting magnet built by Chinese scientists has generated a world-record steady magnetic field of 35.1 tesla, about 700,000 times stronger than Earth’s magnetic field. The development ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking ...

Earth's magnetic field and oxygen levels are inextricably linked, new research suggests. The strength of the geomagnetic field has gone up in lockstep with the percentage of oxygen in Earth's ...

The spatial positioning of magnetic resonance imaging (MRI) images is determined by generating a linearly varying gradient magnetic field through a gradient coil, which plays a pivotal role in the ...

Researchers proposed a completely novel strategy to apply an external magnetic field to modulate spin states, and thereby improve electrocatalytic performance. (Nanowerk News) The job of a catalyst is ...

Researchers proposed a novel strategy for using a magnetic field to boost the efficiency of single-atom catalysts -- thus speeding up helpful reactions used for ammonia production and wastewater ...

The Moon's present lack of a global magnetic field contrasts with evidence of significant magnetization in lunar rocks and large surface regions, a long-standing scientific enigma. A new model ...
