What is Induction?
Induction refers to inducing (causing) a voltage by magnetic means. It is the principle by which power plants change the kinetic energy of a moving turbine, pushed by heated or falling water, into electrical energy. It is also the principle used to extract electrical signals corresponding to information that has been stored in magnetic form in tape recordings or computer disks.
We will also study the concept of inductance, which describes voltages produced by magnetic flux changes resulting from changes in currents. This will be an important concept in understanding AC circuits.
