Taking space the space ratio space of space magnetic space moments space of space the space two comma space we space get
straight M subscript straight S over straight M subscript straight C space equals space fraction numerator 2 INA subscript straight S over denominator INA subscript straight C end fraction
GIven space that space the space current space straight I space and space the space number space of space turns space straight N space remains space the space same.
