You would want to use an electromagnet when you need the magnetic field to be controlled and easily turned on and off, such as in industrial applications like material handling or scrap metal sorting. Electromagnets are versatile as the strength of the magnetic field can be adjusted by changing the electric current flowing through the coil.
Yes, an electric bell uses an electromagnet to work. When the electric current flows through the coil of wire in the electromagnet, it creates a magnetic field that attracts and repels the metal armature, causing it to strike the bell and produce sound.
The electromagnet is only part of the mechinism the whole item is called a solenoid which has a magnetized rod inside the electromagnet when 24 volts is applied the solenoid springs out of the coils of the electromagnet striking the bell. When released the rod returns by use of a spring and strikes another bell. Ding, Dong.
Yes, a compass uses a magnetized needle that aligns with the Earth's magnetic field to determine direction. The Earth's magnetic field is created by the movement of molten metal in its outer core, acting like a giant electromagnet.
A suitable material for the core of an electromagnet would be soft iron or steel. These materials have high magnetic permeability, allowing them to easily magnetize and demagnetize in response to the flow of electric current, making them effective in strengthening the magnetic field produced by the electromagnet.

Yes, you would be able to use electromagnets in space.
A crane or junkyard crane uses an electromagnet to pick magnetic items up. The crane controls the electromagnet by using a a circuit that has a wire wrapped around a piece of metal that can be magnetized that's at the end of the crane's arm. When the circuit completes, the metal at the end of the cranes arm gets temporarily magnetized. When the current stops, the metal get demagnetized and can't pick things up anymore.

Yes, a wooden core would not affect the magnetic properties of an electromagnet since wood is not a magnetic material. For maximum magnetic strength, it is recommended to use magnetic materials such as iron or steel as the core of an electromagnet.
You can use any metal at all for the armature of an electromagnet, but most metals won't influence the electromagnet in any useful way.However if you use a ferromagnetic metal or alloy (i.e. those containing iron, nickel, and/or cobalt) the magnetic field will concentrate in the armature, intensifying the strength of the electromagnet.Ferromagnetic materials can do this because the atoms of iron, nickel, and cobalt have an orbital in one of their internal electron shells containing only one electron instead of the two electrons that other elements have. This makes each atom of these elements a magnet. These atomic magnets naturally orient themselves randomly, so they all cancel out. But when an external field is applied (like from the electromagnet) these atomic magnets rotate to align with it, making the total field much stronger.
An electromagnet is used in an electrical engine, but an electrical engine contains normal magnets too.
