【Abstract】 The finte element equations and the calculating formulas for magnetic field of the LIM are developed on the basis of some reasonable hypothesis by using Maxwell’s equations. The de-tails about its finite element programming are disoussed. It supplies a accurate method for ana-lysing and calculating maganetic field of the LIM. It alsohas practical value to the characteris-tics analysis and design of thf LIM.更多还原
