When a piece of copper wire is moved across magnetic flux, an electromotive force (e.m.f.)
is induced in the wire. This phenomenon is known as electromagnetic induction. If the wire
is connected to form a complete circuit, a deflection of the galvanometer pointer is observed as
shown in Figure 4.18. This shows that induced current is produced. An electromotive force is also
induced in the wire if the magnet is moved towards the stationary wire as shown in Figure 4.19.
