C-Shaped Magnet

The tutorial example C-Shaped Magnet is based on the Magn1 example described in the Examples chapter of the QuickField User's Manual. It might be useful to browse through the Tutorial chapter of the QuickField online help you have not seen it before.

The model consists of a permanent magnet and a steel keeper in the air. The permanent magnets are made of ALNICO. The polarizations of the magnets are along vertical axis opposite to each other.

All dimensions are in centimeters.

Our task is to measure the force acting on the steel keeper versus the distance between the keeper and the magnet. We might also want to explore how the level of coercive force of ALNICO magnet affects on the mechanical force.

We will discuss three different ways of solving this problem.
