Concept

The total reluctance offered by two parallel paths can be calculated similarly to how resistance is calculated in electrical circuits with parallel resistors.

For two parallel magnetic paths with reluctances 'R1' and 'R2', the total reluctance 'RT' is given by:

\(R_T={R_1R_2\over R_1+R_2 }\)

Explanation:

Given, R1 = R= R 

\(R_T={R\over 2 }\)

If the reluctance of the two paths is equal, the total reluctance is half of the individual reluctance.

If one path has a much higher reluctance compared to the other, the total reluctance will be closer to the reluctance of the lower reluctance path.
