Mutual Induction
Our word for the week is Mutual Induction - in physics, the production of an electromagnetic force (emf) or voltage in an electric circuit caused by a changeing magnetic flux in a neighboring circuit. The two circuits are often coils of wire, as in a transformer, and the size of the induced emf depends largely on the number of turns of wire in each of the coils.
Word for the week is chosen by random finger pointing at whatever page opens in my Big Book of Science Terms.
