Iron
Every thing except a conducting wire, battery and a soft iron core is not needed for making an electromagnet
The clay is most suitable for making toys.
terraforming
Its high spontaneous fission rate.
It is tough, strong, wears very well and good corrosion resistance.
Iron - use a bunch of iron nails, wrapped many times with insulated copper wire, if making your own electromagnet.

Yes
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.
copper is suitable for making electricty.
The clay is most suitable for making toys.
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.
