The amount of flux produced by the magnet indicates the strength of the magnet. The more the magnetizing force (MMF), more is the flux produced. The more the opposition to flux path (i.e., reluctance or magnetic resistance) less is the flux produced. This relationship is expressed as
Flux = M.M.F ⁄ Reluctance
Given
M.M.F = 48 Amp-turns
Reluctance = 4 Amp-turns/Weber
Flux = 48 ⁄ 4 = 12 Weber
