The energy, stored within this magnetic field, is released back into the circuit when the current ceases. The energy stored in an inductor can be quantified by the formula \ ( W = \frac {1} {2} L I^ {2} \), where \ ( W \) is the energy in joules, \ ( L \) is the inductance in henries, and \ ( I \) is the current in amperes.
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.
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.
The energy storage capacity of an inductor is influenced by several factors. Primarily, the inductance is directly proportional to the energy stored; a higher inductance means a greater capacity for energy storage. The current is equally significant, with the energy stored increasing with the square of the current.
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
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.
