6 FAQs about [The energy stored in the inductor is the magnetic field energy]
Where is the energy stored in an inductor?
Unlike resistance, inductance cannot convert this energy into heat or light. Instead, the energy is stored in the magnetic field as the rising current forces the magnetic lines of force to expand against their tendency to become as short as possible—somewhat as a rubber band stores energy when it is stretched.
What is magnetic energy in an inductor?
The magnetic energy in an inductor is equal to the potential energy lost by the electrons that went through it before the resistance went to zero. The energy in an inductor is stored in the magnetic field which is generated by the current passing through the inductor.
How does a Magnetic Inductor work?
The energy in the magnetic field of an inductor can be related to the work done to create or change its field. That is, the work done (deliver power) by a voltage source to keep the current flowing through and around a coil.
