 ##Emma's tutorial on motion & sound actuators
 
 Both motion and sound are based on the physics principles of electromagnetism. Both motors and speakers work with coils and magnets. Electricity and magnetism are good friends. If you have electricity you always also have a magnetic field. With a coil you can concentrate this magnetic field's force to a limited space, you amplify it. If you run voltage across a coil, it *becomes a magnet*, so you can move stuff around. This is the basic movement used to make a speaker work, and to make a motor turn. They also have coils.
