The real question should be how do you get current to flow through a compass needle.
Yes
no
An electromagnet is created by running electric current through a coiled conductive wire.

An electromagnet is created by running electric current through a coiled conductive wire.
A magnet created when electric current flows through a coil of wire is called an electromagnet.
When an electric current is reversed in an electromagnet, the magnetic field also reverses.
An electromagnet.
An electromagnet. Unlike other magnets it can be switched on and off.
By passing an electric current through any conductor, a magnetic field will be created. Therefore, a simple electromagnet can be created by connecting a power source to a coil of copper wire.
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
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.
