Solución

This is an example of the slot of the steel keeper simulation, performed with QuickField software.

Problem Type:
Plane problem of DC magnetics.

Geometry:

All dimensions are in millimeters.

Given:
Relative permeability of air μ = 1;
Relative permeability of steel μ = 1000;
Relative permeability of magnet μ = 1;
Coercive force Hc = 500'000 A.

Problem:
Calculate the mechanical force acting on the steel yoke.
