With the miniaturization of electrical equipment, the amount of equipment that uses minute electromagnetic forces is increasing. Therefore, it is important to understand the minute electromagnetic forces that act between parts, such as between multiple magnets.
With magnetic field analysis, you can estimate minute electromagnetic forces at a high accuracy.
In this example, we obtain the minute electromagnetic forces acting on a magnet that is moving translationally.

Electromagnetic Forces Acting on the Magnet

The electromagnetic force acting on the movable magnet in the direction that it moves in is shown in Fig. 1.
The movable magnet is moving translationally away from the fixed magnets. As a result, as the distance moved increases, the electromagnetic forces acting on the movable magnet decrease. You can check these trends even with minute electromagnetic forces.
