For an inspector from Odenton? Sure thing. I'm from (but gone from for 35 years) Pasadena and a retired inspector myself.
Ferro meaning ferrous or containing Fe (iron).
Ferro magnetic means in the case of a relay a coil producing a magnetic field when voltage passes through it and that magnetic field moves a ferrous contact.
A ferromagnetic relay. Is that what you meant?
edit: Welcome to the forums.
Hmm, interesting question from an 'inspector' ?
I'm now thinking maybe should add some definitions that a paramagnetic is a county employee who rides around in a truck with flashin' lights looking for bad relays in traffic lights; or, maybe someone who wires up the MRIs in the hospital ?
And then there is the diamagnetic, who specializes in insulin pumps ?

Well my bad for not knowing and being a 'inspector'
I was reading the NEC ARTICLE 426 Fixed Outdoor Electric Deicing and Snow-Melting Equipment because I am dealing with some heat trace and came across ferromagnetic ground section.

They're just messing with you.
Are you talking specifically about the skin effect article of 426.40 and grounding the ferro magnetic envelope per 426.44?
