A common technique is to solve a series of magnetostatic problems at incremental time steps and then use these solutions to approximate the term ∂ B / ∂ t {\displaystyle \scriptstyle \partial \mathbf {B} /\partial t} .
Uobičajena tehnika je da se reši niz magnetostatičkih problema uz dodatne vremenske korake i onda se koriste ta rešenja da se proceni komponenta ∂ B → / ∂ t {\displaystyle \scriptstyle \partial {\vec {B}}/\partial t} .
