There’s another disadvantage to the use of the flashlight: like many other mechanical gadgets it tends to separate a man from the world around him.

Unlike thermal and electrostatic actuators, magnetic actuators are a familiar part of the macroscopic world. Small magnetic motors (in particular those found in servos) can be found in almost every electronic system in the world. This is in addition to relays, d’Arsonval meters, loudspeakers, and many other devices.
