Which devices on table 3 are powered, entirely or partially, by electromagnetic induction (the phenomeno of a changing magnetic or electric field's effect on electricity or magnetism) ?

The microphone, computer unit, headphone, studio monitor, and the audio

interface are powered entirely or partially by electromagnetic induction.

Although audio cables may be affected by electromagnetic interference,

basically these are supposed to be shielded to work most effectively and do not

use electromagnetic induction to operate. Moreover, the digital audio software

is just a computer application on virtual studios, thus do not also operate on the

EMI principles.
