In summary, an inductor stores energy in the form of a magnetic field, which resists changes in current. When the current is shut off, the energy in the magnetic field gradually dissipates, similar to how a flywheel resists changes in motion. This is due to the voltage across the inductor becoming very large, causing a spark to jump across the ...
