Detailed Solution

When an electric current flows through a copper wire AB as shown in the figure, the wire deflects a magnetic needle placed near it.
The battery is connected to a copper wire and an electric switch. If a magnetic needle is placed near a current-carrying conductor, it defects a magnetic needle placed near it because a magnetic field is created when the current passes through it. Thus, the copper wire AB deflects a magnetic needle placed near it.
