Science attributes the creation of the Earth's magnetic field to the movement of electricity conducting liquids in the molten core of the Earth. Researchers have recently conducted experiments to replicate and study this mechanism.
Experiments conducted in Riga (1999) revealed for the first time that a cylindrical-shaped fluid flow of metal moving in a spiralling motion can generate a slowly growing magnetic field. This was followed by the EU research project MAGDYN (2001-2005), which aimed to show how the generated magnetic field itself is capable of persisting.
The design of these experiments and the theoretical interpretation of the data relied heavily on the statistical simulation models developed by Dr. Sasa Kenjeres and Prof. Kemal Hanjalic of Delft University of Technology's Multi Scale Physics department. Moreover, their theoretical and statistical model was the first to explain and predict the observable effects in Riga.
Based on the findings of Kenjeres and Hanjalic, a new generation of experimental facilities have now been developed in the US (Los Alamos and Maryland, among other places), Grenoble and Russia (Perm). These facilities will allow the Earth's magnetic core to be replicated more realistically than ever before. The new experiments are expected to provide valuable new insights into the Earth's magnetic field.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
