Energy in the inductor is stored in the form of a magnetic field. When current is applied, the energy of the magnetic field expands and increases the energy stored in the inductor. The energy remains constant as long as the current is maintained. If the current is removed, the energy is discharged as the magnetic field contracts.
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. Figure 1 Determining the energy stored by an inductor
This energy is actually stored in the magnetic field generated by the current flowing through the inductor. In a pure inductor, the energy is stored without loss, and is returned to the rest of the circuit when the current through the inductor is ramped down, and its associated magnetic field collapses. Consider a simple solenoid.
Inductance of the coil: The amount of energy stored in an inductor is directly proportional to its inductance. Higher the inductance, higher will be the energy stored. Current flowing through the coil: The energy stored is directly proportional to the square of the current flowing through the inductor.
Thus, the power delivered to the inductor p = v *i is also zero, which means that the rate of energy storage is zero as well. Therefore, the energy is only stored inside the inductor before its current reaches its maximum steady-state value, Im. After the current becomes constant, the energy within the magnetic becomes constant as well.
Self-Induction: Self-induction is the phenomenon where a changing current in an inductor induces a voltage across itself due to its own magnetic field. Energy stored in an inductor is the electrical energy accumulated in the magnetic field created by the flow of current through the inductor.
