Introduction Mthode de contrle qui consiste crer, dans un matriau conducteur, un courant induit par un champ magntique variable. Ces courants induits, appels courants de Foucault, circulent localement, la surface du matriau. La prsence dune discontinuit la surface de la pice contrle perturbe la circulation des courants entranant une variation de limpdance apparente de la sonde. Le passage dun courant dans un solnode produit un flux magntique proportionnel MEC - Martin Viens, prof. Inductance mutuelle Lorsque le flux produit par une bobine est intercept par une deuxime bobine. Notion dimpdance Limpdance dune charge est la mesure de son opposition au passage du courant alternatif Est exprime en ohms symbole De faon gnrale, limpdance dune charge est dfinie par.

Grounding neutralizes the scope The entire scope in neutral so the leaves fall back together. Tags: charging fall induction leaves. Latest Highest Rated. Electrons do not move into the stem as the negative rod repels them. Its overall charge is positive so the leaves repel one another. A negative rod repels the electrons back into the leaves so they become neutral. They fall back together.

This is charging by induction. The process by which an object having an electric charge produces the same charge in a neighboring object without actually touching it.
