As others have described, A relay, whether DC or AC is simply a coil
of wire on a core of suitable magnetic material (usually soft iron)
with a closed magnetic loop which passes through the pivoted armature.


Think 'magnetic material' is the wrong term. It is capable of being
momentarily magnetised - but isn't actually magnetic.


You are being a bit nit-picking aren't you?... You know what was meant
by the shorthand description. In this case "magnetic material" means
"magnetically permeable material" to be precise.


In terms of the OP's question, no. Magnetic suggests it will attract an
armature etc without being externally energised.

I was searching for a single word that means 'magnetically permeable' but
if it exists it escapes me.
