Thesis: Designing gradient micro-coils for electromagnetic control of polishing process in micro-channel performed by abrasive magnetic nano-particles

In the framework of the Master Thesis, the student will be involved in the study and simulation of a mechanical interaction between magnetic nano-particles and designed gradient micro-coils in order to perform and localize the controlled polishing process.

Main objectives are:

Designing, modelling and simulation of magnetic gradient generated by micro-coils (considering geometry and shape effect of the coils);
Study and simulation of the electro-mechanical interactions between the local magnetic gradient and magnetic nano-particles;
Demonstrate a suitable micro-coil design able to perform a localized polishing process.
