The students are familiar with the construction and functioning of electromagnets and, generally, are also aware of their use in a simple relay. The changeover relay used in this experiment is more complicated. It is therefore recommended that the instructor go over the introductory information with the students. This makes it easier for the students to gain an understanding of the relatively intricate circuitry in the experiment.
