5. ELECTRONIC SYSTEMS ENGINEERING TECHNOLOGY TEXAS A&M UNIVERSITY Innovating tomorrow’s products and systems today If a changing magnetic flux flows through a coil of wire, a voltage will be induced in the coil. As you pass a bar magnet through a coil, this creates a changing magnetic field. How else can we create a changing magnetic field?
