Electrocuting oneself

[TheoneandonlytrueGod]

What property does a material have to have in order to get voltage induced by a magnetic field, that wire has and my body doesn't?

You're really pushing me now aren't you?    

I basically know the answer but I'm going to have to do a little research. The short answer is metals react to magnetic fields while living bodies don't in the same way. That doesn't mean that living things are not influenced by extremely strong magnetic fields but they do so in entirely different ways from metals.

I am neither a metallurgist nor a chemist, not a physicist or a biologist.

Electrical properties
Electrical Type Conductor
Electrical Conductivity 1×107 S/m
Resistivity 9.7×10-8 m Ω

See: Electrical Conductivity 1×107 S/m Quote below.

Electrical conductivity in metals is a result of the movement of electrically charged particles.
The atoms of metal elements are characterized by the presence of valence electrons - electrons in the outer shell of an atom that are free to move about. It is these 'free electrons' that allow metals to conduct an electric current.

Because valence electrons are free to move they can travel through the lattice that forms the physical structure of a metal.

Under an electric field, free electrons move through the metal much like billiard balls knocking against each other, passing an electric charge as they move.

The transfer of energy is strongest when there is little resistance. On a billiard table, this occurs when a ball strikes against another single ball, passing most of its energy onto the next ball.
If a single ball strikes multiple other balls, each of those will carry only a fraction of the energy.
By the same token, the most effective conductors of electricity are metals that have a single valence electron that is free to move and causes a strong repelling reaction in other electrons. This is the case in the most conductive metals, such as silver and copper, who each have a single valence electron that moves with little resistance and causes a strong repelling reaction.

Semi-conductor metals (or metalloids) have a higher number of valence electrons (usually four or more) so, although they can conduct electricity, they are inefficient at the task. However, when heated or doped with other elements semiconductors like silicon and germanium can become extremely efficient conductors of electricity.

...The “total body resistance” of a human is composed of the very low (approximately 300 Ω) internal body resistance plus the 2 skin contact resistances. The skin contact resistance will usually be between 1000 and 100,000 Ω, depending on contact area, moisture, condition of the skin, and other factors. The skin thus provides most of the body's protection from electric current.

So even if some voltage was induced in the body the amount induced in the wire would far out weigh that in the body.

Not sure if this will satisfy your concern/question but it is the best I can do for now.
