Electromagnetic induction

Electromagnetic induction. A changing magnetic flux induces a current into a coil. UPDATE (14, 05, 2011): An extended, 15minute video on the topic is now available at or on my website at Demo 1: As the magnet is moved in, the magnetic flux through the solenoid changes and an induced current appears (Faraday s law). The faster the magnet the higher the induced current. If the solenoid is approached first with the other magneti
