Researchers in China have proposed and experimentally demonstrated a revolutionary metamaterial agent, termed metaAgent. This intelligent EM system integrates reasoning and cognitive capabilities, ...
Electromagnetic waves travel at 300,000,000 metres per second (m/s) through a vacuum. Often a phrase is used to help remember the order of the groups of the electromagnetic spectrum such as Roman ...
Electromagnetic induction can create a voltage by movement of a conductor in a magnetic field. This voltage can make current flow. Transformers use electromagnetic induction to change the voltage ...
Jean-Michel Ménard, an Associate Professor of Physics from the Faculty of Science, and a team of researchers have paved the way for developing devices capable of upconverting electromagnetic ...
It is also grade school science to show that neither an electromagnet nor a permanent magnet will pick up nonferrous items like copper or aluminum. While technically not an electromagnet ...
