Yes, you would be able to use electromagnets in space.

To make distant things closer they use a telescope, to make close things larger they use a sense or magnifying glass, to make very small things larger they use a microscope. to make incredibly small things clearer they use mathematics.
People make use of constellations by helping their way traveling
To make the image clearer on a microscope you can use the focusing lens.
He wound wire around it to make a tranformer.
u need 2 provide more information"Which of these materials would be best to use for the core in order to make the strongest electromagnet to?"u need to provide what "these materials" are
how to make road rail signal using electromagnet
electromagnetically
yes. but it also wastes energy as sound
yes it does
No.
A choke, an electromagnet, an electric motor stator, an electric motor rotor, etc. all depending on details of construction and use that are unstated in the question.
Not generally, although MacGuyver could make an electromagnet with a toothpick and a spool of wire.
An electromagnet drives the stereo speaker to provide the sound.
The poles of an electromagnet can change depend inf on the current supplied.
To chew on it.
