A magnetic field that is generated around a conductor when a current flows through it. Electromagnetic induction is also the creation of an electrical pulse in a conductor when a magnetic field moves ...

This is called electromagnetic induction close electromagnetic inductionThe production of a potential difference (voltage) when a conductor, such as a wire, is moved through a magnetic field or ...

1. When ac excitation is applied to the transmitter (lower) coil, it generates a magnetic field. When the receiver (upper) coil is placed in proximity and aligned with the transmit coil, that magnetic ...

Nitrogen, a chemical nutrient needed by many growing crops, can accidentally end up in surface or subsurface water. Now an Agricultural Research Service scientist is using electromagnetic induction ...

Electromagnetic induction can create a voltage by movement of a conductor in a magnetic field. This voltage can make current flow, and the effect is used in electricity generation and microphones.
