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 ...

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 ...

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 imaging (EMI) is a well established imaging technique, developed over several decades. It has been widely used to assess cracks in metallic structures and to detect and ...

A WISE driver keeps an eye on the fuel gauge, to make timely stops at filling stations. For drivers of electric cars, though, those stations are few and far between. The infrastructure needed for ...

Northern Ghana, a semi-arid region with rainfall occurring only 4 to 5 months in a year, has a long dry-season that renders farmers unemployed for 7-8 months in a year. This contributes to widespread ...
