An electric current through a copper wire
-
Creates a magnetic field around the wire.
-
Creates a longitudinal magnetic field in the wire.
-
Magnetizes the wire.
-
Does not create a magnetic field.
That's Correct!
It's Wrong!
When an electric current flows through a copper wire, it creates a magnetic field around the wire. This is due to the interaction between the moving charges (electrons) in the wire and the magnetic field they produce. This phenomenon is known as electromagnetism and is the basis for many electrical devices such as motors and transformers. The magnetic field created by the current can be detected using a compass needle or by placing a small magnetic material near the wire.
