Do electronic stud finders work on plaster walls?

Some do, but plaster and lath can give mixed readings. Models with a deeper scan mode tend to handle older walls better.

What is the difference between an electronic and a magnetic stud finder?

An electronic finder senses changes in wall density. A magnetic one finds the metal screws or nails that hold drywall to the studs.
