Because of this, you'll be able to create a magnetic subject with electricity, and you'll create electrical present with a magnetic subject. The name "inductively coupled" comes from this process -- the magnetic field inducts a present in the wire. You'll be able to learn more in How Electromagnets Work. These were meant to be disposable tags that could possibly be utilized to inexpensive merchandise and made as common as bar codes.<br>
