Mutual Inductance of Two Loops

[file: mloop.mcd]

Formulas included in this spreadsheet:

  • Mutual inductance of two loops MLOOP()

Variables used:

  • r Separation between loop centers (in.)

  • A1 Surface area of loop 1 (in.2)

  • A2 Surface area of loop 2 (in.2)


    (We assume the loops are flat,
    and that their faces are
    oriented parallel to each
    other for maximum coupling)


The loops must be well separated for the MLOOP() approximation to work:

       and      

Mutual inductance of two well-separated loops (nH):
