What is the difference between a magnetic and elective electric field?

Question

I saw the term "elective" in an article about Intel's wireless electricity product development. I quick search of the net found no answers.

Answer 1

It was most likely a typo, meant to say "electric field" or a highly incompetent editor.  Wireless electricity relies on changing electromagnetic fields.  Electric and magnetic fields are intertwined based on Maxwell's equations.

Answer 2

This is a piece of drivel PR announcement.  An "elective field" is your college minor class choices.  I think the made-up scientific-sounding phrase is trying to reassure people in advance that somehow, a building using this power transmission method (in effect, a big transformer) is different than being bathed in electromagnetic waves from power lines. It is the same thing -its all electromagnetic waves, the frequency and power level may vary. (The idea is old, and incredibly inefficient in principle.  I note there is no comment on improved efficiency of transmission)
