Suppose I buy a roll of thin wires, install multiple hooks at the

Would that make a great AM antenna? Would it work?

Hello,
A large loop does receive more signal, but will also receive more
noise/interference. You should optimize for best signal to noise
ratio. Often, larger does not mean better.
When you make a loop as large as your room, the wire may run close to
mains wiring or equipment that generates interference (that may result
in bad reception). You can better make a small portable loop that
you can move around to find the sweet spot/orientation for best
reception. You can use whatever insulated copper wire to make the
loop.
Best regards,
Wim
