3D Magnetostatic Analysis of Magneto-Inductive Devices for NDT

This work presents the 3D magnetostatic numerical analysis based on Finite Integration Technique applied to the design of magneto-inductive devices for the Non Destructive Testing (NDT) of ferromagnetic ropes. The problem is characterised by several design aspects and by the high saturation level reached in the device core and in the rope under testing. CST EM STUDIO® was used for the virtual prototyping which entailed the the optimisation of permanent dimensions using 3D non-linear magnetostatic optimisation. Measured versus simulated results are presented.
