The simplest component utilising electro-magnetic interaction is the coil. The coil is a buffer component which stores energy in magnetic form. Aircored coils are frequently used (for example in loudspeaker filters), but coils with a core of (possibly gapped-) magnetic material are more common because of their increased inductance (or reduced size), which comes at the cost of reduced maximum field strength and increased non-linearity.
