the shape of the core and the distance between the poles affect the strength of the electromagnet
An electromagnet needs an electric current to flow through a coil of wire in order to generate a magnetic field. The strength of the magnetic field can be controlled by adjusting the amount of electric current flowing through the coil. Additionally, using a ferromagnetic core, such as iron, can enhance the strength of the electromagnet.
The rotating electromagnet in an alternator is called the rotor.
The name "electromagnet" comes from the combination of "electricity" and "magnet." When an electric current flows through a wire, it creates a magnetic field around the wire, leading to the creation of an electromagnet. This device can be turned on and off by controlling the flow of electricity.
Power or might.
I'm not sure what this question really means - should it be more like "what two things affect the force between two electric charges?" If this is correct then the answer is probably: 1. The amount of charges. 2. The distance between the charges.

That is an electromagnet.

Yes, an electromagnet can work without a nail. The core material affects the strength of the magnetic field produced, with a nail being a common choice due to its magnetic properties. Other core materials like iron or steel can also be used to create an electromagnet.
An electromagnet is only magnetic when an electric current is run through it.
It is changing force

Gertrude is the name of several things. It is also a female name meaning spear, or strength from the Germanic language. Now, do your own research.
