A – The coil is at 0°. The coil is moving parallel to the direction of the magnetic field, so no potential difference is induced. B – The coil is at 90°. The coil is moving at 90° to the ...
The induced voltage produces an induced current if the conductor is connected in a complete circuit. As with all currents, the induced current creates a magnetic field around itself. Note that ...
Philip Morrison and Guiseppe Cocconi analyzed how two civilizations separated by many light years of space might use electromagnetic radiation to communicate. Electromagnetic radiation is the general ...
Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves.
