Magnetic microsystems applications - 4PMTMMA2

Goal(s)

Understand why magnetic interactions often benefit from scale reduction laws:

• fields and gradients generated by magnets and conductors,
• volumic force density between these elements.
  Understand how such iteractions are exploited in MEMS.
• what materials, how they are integrated
  Discover various applications :
• both in R&D and in coercialy available devices.
