Did you know Earth's magnetic field is on the move? Recent studies reveal it's shifting at an astonishing rate—10 times ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth.

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...

You can test stir bar behaviour by filming through the side of a vial or using a magnetic material (nickel or iron granules) ...

The complex motion modes of surface microwalkers rely on magnetic torque generated by rotating/oscillating magnetic fields. Actuation systems based on rotating permanent magnets exhibit considerable ...

Magnetic fields are everywhere in the universe. Of course, there's Earth's magnetic field, which deflects dangerous cosmic radiation, wiggles our compasses, and guides flocks of migrating birds.

In contrast to electromagnetic fields, spin-polarised currents act very locally and can be steered with a precision of less than a nanometre. Such currents could be used to address electronic circuit ...

The primary hurdle is ‘eddy damping’, a form of energy loss that occurs in oscillating systems. Traditionally, this phenomenon has presented a challenge for using magnetic levitation in sensor ...

In brief Using oscillating electromagnetic field in ion traps limits the currently achievable number of qubits in quantum computers. Researchers at ETH have now created an ion trap on a ...

This non-equilibrium regime is at the core of quantum optics and quantum computing technologies. From our examination of this non-equilibrium regime in magnetic materials, while borrowing ...

3) Vector P (in Figure 5 and Figure 6) represents the magnetic field which is produced by the current I that is generated by Lentz law: P opposes the variation of the magnetic flux through the ...
