magnetic pull
the force of attraction between two magnetic poles of opposite polarity

Note – In the case of two parallel pole faces of equal area separated by a very small air gap, the magnetic pull is given by:

force d'attraction entre deux pôles magnétiques de polarités opposées

Note – Dans le cas de deux faces polaires parallèles séparées par un entrefer très petit, la force portante est donnée par:

F= 1 2 μ 0 B 2 dA MathType@MTEF@5@5@+=feaagCart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHXgaruavP1wzZbItLDhis9wBH5garmWu51MyVXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeaaciWacmGadaGadeaabaGaaqaaaOqaaiaadAeacqGH9aqpdaWcaaqaaiaaigdaaeaacaaIYaGaaGPaVlabeY7aTnaaBaaajeaybaGaaGimaaWcbeaaaaGcdaWdbaqaaiaadkeadaahaaWcbeqcbawaaiaaikdaaaGccaaMc8oaleqabeqdcqGHRiI8aOGaaeizaiaadgeaaaa@44A2@
