Uncle Al re magnet wire |

I would normally assume "magnet wire" to be copper winding wire as used in
transformers and motors. But are you sure about this? Or is this an
aluminium copper alloy wire uncommon in my world?

Sorry, my error. Make that "piano wire." I've got a busy week here
through next Monday and don't have be contemplative and languid. Crap
in the fan and all that.

If you heat piano wire red hot in a forge and hammer it on an anvil,
the result is called wrought iron and is harder than aluminium.

Hi Uncle-A Seems Faraday did a lot with a magnetic wire.it could
caused things to move. So in reverse a magnet could cause a current
carring wire to move. He suspended a piece of wire above a bowl of
mercury in which he had fixed a magnet upright He connected the wire to
a battery and it began to rotate. Simple electric motor,and nice
experiment for 7th grade. Electricity and magnetisim are two sides to
the same coin. Bert

You could be a bit further off the mark, but not today.
Faraday used Copper wire, not magnetic wire.
TODAY we call such thinly shellacked wire magnet wire.
Back then it was likely not coated the same way. Either way the wire
was itself not magnetic.
It STILL is not magnetic.
When one passes an electrical current through a conductor, it
exhibits a magnetic field. When the current is removed so too is the
field. Magnetic wire retains its magnetizations, and was used
specifically for audio recording purposes.

Some of then might be. Most are wrought iron; none, I am sure, are cast
iron.

I was referring to my previous post where I told him that beating
piano wire when red hot does not make it wrought iron, which is what
he posted.

If you heat it and beat it, it does NOT turn into wrought iron.

Yes, they really should iron out their difficulties in another thread.
Or should that be wire? :-)

I missed the original post. Magnet wire is enamel coated copper wire.
Aluminum would be too lossy. Can someone explain .."then spontaneously
