Magnetic path length

Magnetic path length, path length or magnetic path, typically represented by the symbol $l$ for “length” 1)2)3) or MPL4) - is the effective path taken by the magnetic flux in a magnetic core or magnetic circuit. The path is measured in the units of length (e.g. metres).

The concept of path length is used in calculations such as: deriving the value of magnetic field strength H from the magnetising current5) in a closed magnetic circuit6), magnetic reluctance7), effective permeability8), and many more.
