Abstract
A coil includes a first portion, a second portion, a third portion, and a fourth portion. The first portion is wound in a first direction around a first core and the second portion is wound in the first direction around a second core. The third portion is wound in a second direction that is different from the first direction around a third core such that the third portion is decoupled from the first and second portions. Additionally, the fourth portion is wound in the second direction around a fourth core and decoupled from the first and second portions. An inner area is formed by arranging the portions and a voltage is induced in the coil if an electrical conductor is placed in the inner area.
