The inductor works like a capacitor and doesnt dissipate energy. When the current increases the current derivative has a positive value and the power is positive.

It stores electric energy in the form of the magnetic field during the charging phase and releases the same energy to the circuit in the decay phase.

Energy store in inductor. The energy is related to the current magnitude of the current. Energy in an inductor. Inductors store energy in the form of a flowing current.

Considering a pure inductor l the instantaneous power which must be supplied to initiate the current in the inductor is. Energy stored in an inductor suppose that an inductor of inductance is connected to a variable dc voltage supply. If you add up the energy for each charging cycle over 1 second this will give you the power.

When a electric current is flowing in an inductor there is energy stored in the magnetic field. Energy stored in the inductor is the multiplication of current through inductor and voltage across it. When the current is constant the derivative is zero and no additional energy is stored in the inductor.

The supply is adjusted so as to increase the current flowing through the inductor from zero to some final value. The energy stored in the magnetic field of an inductor can be calculated as w 12 l i 2 1 w energy stored joules j l inductance henrys h. The total energy in the inductor at any given time is the integral of the power from minus infinity to that time.

So the energy input to build to a final current i is given by the integral.
