Magnetic path length

Magnetic path length (MPL) is the effective length of a closed magnetic loop inside a magnetic core made of ferromagnetic material which may be also gapped.[1][2] MPL is relevant in transformer and inductor design and more generally in all kinds of magnetic reactors, such as in magnetic amplifiers and electromagnets.
