【Abstract】 By establishing a mathematical model and using the electromagnetic field theory,the numerical computation method and calculus technique,etc.,the mutual inductance between the two solenoids was obtained. Furthermore,the formula of expressing the above- said electromagnetic force was achieved by adopting the virtual work principle,with the computing method and ideology mainly analyzed and researched. By using the Matlab mathematical software,the distribution of the two coaxial electric cylindrical solenoids’ electromagnetic lines was simulated and the computed result was further verified. The image of relation between the electromagnetic force and their corresponding variables was also simulated.更多还原
