Permanent magnets play a crucial role in medicine due to its field strength, tunability of field and gradient distributions, as well as practical implementation. In a new study published in KeAi ...
A flip-flop of Earth’s magnetic poles between 42,000 and 41,000 years ago briefly but dramatically shrank the magnetic field’s strength — and may have triggered a cascade of environmental crises on ...
The Earth's magnetic field helps protect life from energetic particles that would otherwise arrive from space. Mars now lacks a strong magnetic field, and the conditions on its surface are considered ...
