Magnetics, in general, refers to any electronic device that employs the use of magnetic fields to accomplish its intended purpose. An inductor is a classic circuit component that converts electrical energy to magnetic energy (and vice versa). Inductors and capacitors are the two types of energy-storage components used in the design of analog filters. Together the inductor and capacitor can be used to remove high-frequency components (lowpass filter), remove low-frequency components (highpass filter), remove only a specific frequency range (bandstop) or pass only a specific frequency range (bandpass).

Electrical transformers are simply two inductors with strong mutual coupling between them. Step-down transformers reduce the voltage from the input power source to an amplitude that is less dangerous and also more practical in businesses and households. Step-up transformers increase the voltage for more efficient transmission over long distances of power lines. Transformers are essential to the distribution of AC power.
