Multiple droplets of a magnetic fluid have been used to create all of the fundamental logic circuits within a computer. Created by researchers in the US, the circuits are made by having the ...

Inspired by ideas and techniques for cooling atomic gases, an experiment demonstrates how the temperature of micrometre-scale electronic devices can be lowered using solid-state quantum circuits.

The questions in this quiz are suitable for GCSE physics students who are studying electrical circuit symbols, electrical charge and current, potential difference, factors that affect resistance and ...

The first circuit of ultracold atoms has been unveiled by physicists in the US. The team has already shown how the atomic current in the circuit can be controlled precisely and believes that similar ...
