I derive the formula for energy stored in an inductor as follows: energy = E(t) = ∫ t0t v(τ) i(τ)dτ energy = E ( t) = ∫ t 0 t v ( τ) i ( τ) d τ However the book that i'm using defines inductor energy as just: then they go onto to calculate the energy of a 2 Henry inductor with current flow of :
To determine the energy stored by an inductor, consider the circuit in Figure 1. Although the voltage remains constant, the current steadily increases as time elapses. In resistance circuits with constant current and voltage, the energy transferred is W = Pt = VIt.
An inductor stores energy when a current flows through it. The energy stored in the inductor is given by the formula: U = 1/2 L I2. When the switch is closed, this energy is stored in the inductor. However, when the switch is opened, this energy is dissipated in the resistor. An inductor doesn’t like change!!! When the switch is opened, the inductor will try to maintain the current that was flowing through it before the switch is opened.
The energy stored in an inductor resides in its magnetic field, which has an instantaneous energy density of: Wm(t) = μ | →H | 2 / 2[Jm − 3] Since the magnetic field is uniform within the volume Ad of the rectangular inductor of Figure 3.2.1, the total instantaneous magnetic energy stored there is:
An inductor stores energy in its magnetic field. As the current through the inductor increases, it forces the magnetic lines of force to expand against their natural tendency to shorten. This expansion stores energy in the magnetic field, similar to how a rubber band stores energy when stretched.
This results in the flow of current. it can be said that the, energy stored in the the inductor is due to the temporary alignment of these dipoles. but few magnetic dipoles can not attain their initial configuration. hence, we say pure inductor is not present practically. Scientists know that the electric fields and magnetic fields are co-related.
Inductors are a great choice here for energy storage because as discussed earlier, inductors love stable current. The inductor voltage changes to maintain current. This ability allows the switching controller to store the energy it needs externally in order to maintain a desired output voltage of the regulator circuit.
Valor de un inductor.

Inductor values can be determined mainly by two ways, namely text coding and color coding methods. Some inductors are larger in size, thus often their values are printed on their body (name plate details). However, for smaller inductors, abbreviation or text is used because there may not be enough room, for printing the actual value on it.

The inductor becomes a voltage source for the rest of the circuit. And since the current in an inductor can''t change instantaneously, but the voltage can, the polarity of the inductor reverses. The voltage across the inductor (at the exact instant of change) becomes 5V in the opposite direction from when it was charging.
