Therefore, the energy stored by an inductor as the current rises from zero to Im is \ [W=V\times \frac {1} {2} { {\operatorname {I}}_ {m}}\times t\] Since the rate of change of current is constant, Inductor voltage becomes \ [V=L\frac {di} {dt}=\frac {L { {\operatorname {I}}_ {m}}} {t}\]
As the current increases, the inductor’s magnetic field grows stronger, storing energy. Conversely, if the rate of change in current is swift, the inductor would induce a potentially high voltage, which can lead to fascinating behavior in oscillatory circuits or resonant systems. By utilizing
The consequence of this is to increase the energy transferred from the voltage source to the inductor. Thus, increasing the gap increases the energy stored, though with no increase in the flux (Φ = Vt) but with an increase in the current (I = R Φ). 1 The term air gap is commonly used to indicate a
This energy storage is dynamic, with the magnetic field's intensity changing in direct response to the variations in current. When the current increases, the magnetic field strengthens, and when the current decreases, the field weakens. The energy, stored within this magnetic field, is released
