Magnetic resonance imaging (MRI) is a non-invasive biomedical imaging technique that uses a strong oscillating magnetic field to induce endogenous atoms such as hydrogen, or exogenously added ...

'ZDNET Recommends': What exactly does it mean? ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources ...

One of the many unseen forces to which you owe your existence is magnetism. If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely ...

Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from solar radiation — and helps guide the migrations of many animals. Loggerhead ...

It’s a simple magnetic ring attached to a non-magnetic finger ring that doubles as a kickstand. But what if both rings were magnetic? What if both of them were the same size? What if each of ...

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 ...

This map and an internal magnetic ‘compass’ rely on distinct mechanisms, implying that turtles have two magnetic senses. We developed a magnetic-coil system that could replicate the magnetic ...

All the magnets on the LHC are electromagnets. The main dipoles generate powerful 8.3 tesla magnetic fields – more than 100,000 times more powerful than the Earth’s magnetic field. The electromagnets ...
