When making an electromagnet, the moving electrons come from the flow of electric current through a wire or coil of wire.
Moving electrons in an electromagnet come from the flow of electric current through a wire or coil of wire.
The piece of iron inside an electromagnet is called a "core". It serves to increase the magnetic field strength when current passes through the electromagnet, making it more effective at attracting or repelling objects.
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.
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.
Every thing except a conducting wire, battery and a soft iron core is not needed for making an electromagnet
Yes
When making an electromagnet, the moving electrons come from the flow of electric current through a wire or coil of wire.
No, the electromagnet is not made weaker by making the core larger. It can be made weaker by decreasing its current and/or turns of coil.
By making it an electromagnet. Include it in a circuit.

It needs more than an electromagnet. You have an electromagnet with an iron diaphragm in the magnetic field. When the audio current from the amp flows in the electromagnet, the diaphragm moves at the same frequency, making the sound that you hear.
Moving electrons in an electromagnet come from the flow of electric current through a wire or coil of wire.
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
