6.3.4. Magnetic Actuation

Try these first

1. 1.

   What force is generated by the interaction of current and magnetic fields in MEMS?

   Hint

   It relates to charged particles in magnetic fields.

2. 2.

   List one application of magnetic actuation.

   Hint

   Think of where tiny switches might be used.

3. 3.

   What principle does magnetic actuation rely on?

   • Electromagnetic induction
   • Lorentz Force
   • Thermal expansion

   Hint
