The idea that plate motions are caused by electromagnetic forces has not been widely proposed as a mechanism of plate motions. The most accepted mechanism is the theory of plate tectonics, which suggests that plate motions result from the movement of convection currents in the Earth's mantle. Other proposed mechanisms include ridge push, slab pull, and mantle plumes.

What is a photo plate?

A photo plate is usually a glass, or metal plate, coated with light sensitive chemicals. Until used it was kept in the dark. It was placed in the camera and exposed to the light of the scene, then removed, and stored in the dark, until it could again be chemically treated to reveal and fix the image on the plate. The glass plates produced images that could later be used to produce a copy of the image printed on paper by shining a light through them. Metal plates produced the image on the plate itself. They could be the end result, or be used in specific printing techniques to make copies in a printing press. The metal and glass plates were replaced by plastic film, and now the film has been replaced with electronic sensors. Even the term photo plate has been replaced with the term photo mask.
