When a electric current is flowing in an inductor there is energy stored in the magnetic field. See inductor is an energy storage device it stores energy in form of magnetic field by virtue of kinetic energy of electrons and as current flows in an inductor it produces magnetic field.

Relation Between Magnetic Fields And Inductance
Kinetic inductance is observed in high carrier mobility conductors and at very high frequencies.
Kinetic energy inductor. The kinetic energy that corresponds to a desired velocity is. A conservative guess at coilgun efficiency is 1 or in a highly tuned coilgun it might reach 2. Kinetic inductance is the manifestation of the inertial mass of mobile charge carriers in alternating electric fields as an equivalent series inductance.
To that end sections ii and iii establish the basic harvesting theory on which illustrative piezoelectric and electrostatic switched inductor converter examples presented rely to generate a net energy gain. Ke m v2. Considering a pure inductor l the instantaneous power which must be supplied to initiate the current in the inductor is so the energy input to build to a final current i is given by the integral using the example.
The result will be that instead of the current instantaneously becoming remember ohms law it will increase slowly to as the inductor steals energy to store in the magnetic field. But the inductor will respond by effectively converting the kinetic energy of the current into magnetic energy. Energy in an inductor.
Ics designed to harvest ambient kinetic energy in vibrations with piezoelectric and electrostatic transducers. Also inductors have high no of turns low resistance and are made of iron core provides low reluctance path. The total potential energy needed depends on the efficiency you can build and what velocity you want to achieve.
The potential energy in a capacitor is stored in the form of electric field and the kinetic energy in an inductor is stored in the form of magnetic field.
