Question

A coil of wire wrapped around an iron core will make the core __________ when current flows.

Answer 1

It will magnetize it

Answer 2

Uhm ok, thanks. !

Answer 3

a coil if insulated wire around soft-iron core should make it behave like an electro-magnet.

However if it isn't a 'soft'-iron one, the magnetization may be permanent, or atleast with a greater hysteresis (degree of retentivity of the magnetic character).
