Energy Stored in Inductor: Theory & Examples
This reflects how changing the current through an inductor can significantly impact the energy it stores. It''s crucial to note that when current is first applied to an inductor, the energy of the magnetic field expands, and the increase in energy is stored in the inductor. As current is maintained, the energy remains constant.

Inductor
Energy stored in an inductor. One intuitive explanation as to why a potential difference is induced on a change of current in an inductor goes as follows: When there is a change in current through an inductor there is a change in the strength of the magnetic field. For example, if the current is increased, the magnetic field increases.
Can you store energy in an inductor and use it later?
The magnetic field which stores the energy is a function of the current through the inductor: no current, no field, no energy. You''ll need an active circuit to keep that current flowing, once you cut the current the inductor will release the magnetic field''s energy also as a current, and the inductor becomes a current source (whereas its dual, the …
