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 ...

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 (EMI) has emerged as a pivotal non‐invasive tool for characterising soil electrical conductivity, offering insights into subsurface heterogeneity that are of critical ...
