The reluctance in a magnetic circuit is given by:
\(R={MMF\over Flux}\)
\(R={l\over μ A}\)
where, l = length of the magnetic path
μ = permeability of the material
A = cross-sectional area
Explanation
In a magnetic circuit, reluctance is analogous to resistance in an electrical circuit. When different magnetic materials are connected in series (as in a ring), the total magnetic reluctance is the sum of the individual reluctances, just like resistances in a series circuit.
\(R_T=R_1+R_2+R_3\)
