IT is a consequence of Faraday‘s law of electromagnetic induction that when a large body of water moves in the presence of the earth‘s magnetic field, an electromotive force is set up across ...

Satellites have managed to detect faint electromagnetic signals generated by ocean tides, suggesting that space-born sensors ...

The role of electrons and their negative charge in electric current is well established. Electrons also exhibit other ...

Physicists in Germany have developed a new way of defining the standard unit of electrical resistance. The advantage of the new technique is that because it is based on the quantum anomalous Hall ...
