Because of this, you possibly can create a magnetic area with electricity, and you may create electrical present with a magnetic discipline. The title "inductively coupled" comes from this process -- the magnetic area inducts a present in the wire. You'll be able to learn more in How Electromagnets Work. These have been meant to be disposable tags that could be applied to less expensive merchandise and made as common as bar codes.
