Abstract :
The optimal design of delicate magnetic scale for linear relation between the magnetic flux density and force is presented. The magnetic scale utilizes magnetic levitation force. The linear relation between magnetic flux density and force is shown by implementing additional metal structure on the magnet. The optimization is performed by using finite element method (FEM) and evolution strategy (ES)
