Short answer: A human body is not the sort of material that reacts to magnetic fields (in the sense you suggest). And yes there are electrical currents produced by the body but not induced by an external magnetic field.
You are constantly moving through the earths magnetic field but there no EMF(potential [voltage]) induced in your body and if there is it is so minuscule it cannot be measured with any instrument presently available. That is the first reason.
Second reason: it takes a completed circuit before any current can be flow.

V = voltage induced (EMF(potential [voltage])) (can be roughly analogous to water pressure) only in a metallic wire.
C= Current: movement of electrons in the wire (again roughly analogous to the movement of water through a pipe).
R = Resistance: Some substance that resists (impedes) the flow of electrons. Roughly analogous to water being forced through a smaller pipe.
There is no voltage induced in the resistor only an impediment to the flow of electrons (current).
A conductor of electricity that is not connected to some sort of load is known as an open circuit (think blown fuse [tripped circuit breaker] in your house therefore no current flows to a load (light bulb, electric stove, etc);

So in the cited example (a wire connected to two parts of the body) is a closed circuit and therefore a current would flow if you moved fast enough around the earth (a magnetic field). It would induce a current of sufficient quantity to kill you.
Your body actually resists the current flow and in the process generates heat just as a resistor in an electric circuit does. It is the current that kills you not the voltage. Electric Chairs kill with current not voltage. As I said before check out https://en.wikipedia.org/wiki/Static_electricity and https://en.wikipedia.org/wiki/Van_de_Graaff_generator

Gack, I thought this would be a quick reply and a simple explanation. BTW are you familiar with or work with electricity?
