When the chassis of a car is moved into a painting chamber, a mist of paint is sprayed around the chassis. When the car is given a sudden electric charge, the mist is attracted to it, and the car is quickly and uniformly painted.
What does the phenomenon of polarization have to do with this?
1. The car is magnetic; with some polarization of the paint, it will be easier for the paint to be attracted to the car.
2. The paint particles in the mist are polarized and as such are attracted to the charged chassis.
3. The air is polarized and makes the paint flow uniformly.
4. The car is polarized and easily attracts paint particles.
