The reluctance in a magnetic circuit is given by:
\(R={MMF\over Flux}\)
\(R={l\over μ A}\)
Explanation
In a magnetic circuit, reluctance is analogous to resistance in an electrical circuit. In the given question and diagram, two magnetic paths, BE and BCDE, are in parallel, forming a parallel magnetic circuit.
In a parallel magnetic circuit, the magnetomotive force (MMF) or Ampere-Turns (AT) across parallel branches is the same, just like voltage in an electric parallel circuit.
Hence, the correct answer is option 2.
