The real question should be how do you get current to flow through a compass needle.
The needle of the compass will align itself with the magnetic field produced by the electromagnet due to the flow of electric current in the coil. The compass needle will point in the direction of the magnetic field lines, which are generated by the current passing through the coil of the electromagnet.
An electromagnet is created by running electric current through a coiled conductive wire.
Usually it's a permanent magnet. You could use an electromagnet instead, but doing so is considerably harder from an engineering standpoint.
An electromagnet is created when electric current flows through a coil of wire. This coil acts as a magnet when current is passed through it, allowing it to attract magnetic materials and exert a magnetic field. The strength of the electromagnet can be controlled by adjusting the amount of current flowing through the coil.

A magnet created when electric current flows through a coil of wire is called an electromagnet.
An electromagnet.
A simple electromagnet is created by wrapping a wire around a core material, such as iron, in the shape of a coil. When an electric current flows through the wire, a magnetic field is generated around the coil, turning it into an electromagnet.
An increasing electric current moving into an electromagnet will become stronger in its magnetism. As the atoms align the increasing magnetism will stop at one point, making the electromagnet as strong as it can be.
