Physical interpretation of Reluctance

  1. Oct 3, 2004 #1
    Hi,

    I would like to know what is the physical interpretation of magnetic reluctance.
    Also I would like to know why the magnetic flux in a magnetic circuit composed of different magnetic materials should be the same?

    Thank you.

    we know from ohms law that: e=i times r
    when we consider inductors in circuits with frequencies we substitute r with xc (inductive reactance).
    the formula is: Xl (inductive reactance)=2 * pie *f (freq.) * L
    the only way "the magnetic flux in a magnetic circuit composed of different magnetic materials should be the same" is if, the inductance of the inductors are the same.
    ie: ferrous material # 1 has 10 windings, and this inductance is equal to ferrous material # 2 with 12 windings, as material #'2's permiability is lower.
