Steel keeper

QuickField simulation example

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

Problem Type
Plane-parallel problem of DC magnetics.

Geometry
Steel keeper A simulation of permanent magnet and a steel keeper in the air, performed with QuickField software. Steel Steel Magnet 10 cm 20 cm 40 cm 10 cm 20 cm 10 cm 10 cm

Given
Relative permeability of steel μ = 1000;
Relative permeability of magnet μ = 1;
Permanent magnet coercive force Hc = 500 kA/ΠΌ.

Task
Calculate the mechanical force acting on the steel yoke.

Results
