Paramagnetic paint changes color at the touch of a button

November 09, 2007

Before the vehicle is painted, a special polymer containing the special ‘paramagnetic’ iron oxide particles is applied to the car’s body. An applied electric current then adjusts the spacing of small crystals within the iron oxide particles and therefore affects their ability to reflect light and change color.


When the vehicle is switched off, the car returns to a default color of white.
