Other AbstractGood visualization of magnetic flux lines should meet the rule that the density of magnetic flux lines reflects the magnitude of magnetic field at one point and the tangential direction of every magnetic flux line accords with the magnetic field.So the visualization of magnetic flux lines needs to solve the choice of seed points of magnetic flux lines and the tracing of lines accurately and reasonably.A seed point is the starting positon of one magnetic flux line.The rule of choice is the density of lines traced by seed points accords with the magnitude of magnetic field at one point.The traditional way is a statistical algorithm based on practical data .This paper proposes two schemes based on physical constraints:equivalent magnetic flux and the equivalent reduction of magnetic flux density.The two methods are based on strict math deductions. Finally,we traced the magnetic flux lines through classic fourth order runge-kutta method,and got satisfied results.
