   Define thermal actuators.

   Hint

   Think about how heat affects materials.

2. 2.

   What principle do magnetic actuators operate on?

   Hint

   Consider what magnetic forces can do.

3. 3.

   What do thermal actuators rely on to function?

   • Electrical energy
   • Heat expansion
   • Compressed air

   Hint

   Think about what happens when materials heat up.

4. 4.

   True or False: Magnetic actuators can be used in precise positioning applications.

   • True
   • False

   Hint
