Concept:

In a magnetic circuit, magnetic flux () behaves similarly to electric current in an electrical circuit. In a series magnetic circuit, all the magnetic components (like cores and air gaps) are arranged in series, and the same flux flows through each part, regardless of the varying reluctance of the individual sections.

Key Principle:

Just as current remains the same in a series electrical circuit, magnetic flux remains constant in a series magnetic circuit.

Evaluation of Options:

Option 1: the same – Correct
Same flux flows through all elements in a series magnetic circuit.

Option 2: different –  Incorrect
Flux would differ only in parallel magnetic paths, not in series.

Option 3: zero – Incorrect
Flux exists as long as there is magnetomotive force (mmf).

Option 4: infinite –  Incorrect
Infinite flux is not physically possible.
