Directions: Open the Faraday Law simulation Links to an external site. and discover what you can about induction. Make a list of ways to cause induction and answer below questions. Flip Polarity: Flipping the polarity of a magnet essentially changes the direction of the magnetic field. According to Faraday's Law, a change in the magnetic field within a closed loop of wire induces an EMF. Therefore, flipping the polarity of the magnet induces an EMF. Move Magnet: Moving a magnet closer to or farther from a loop of wire also changes the magnetic field within the loop. This change in the magnetic field induces an EMF. The faster the magnet moves, the greater the change in the magnetic field, and the greater the induced EMF. Use two different loops: Increasing the size of the loop increases the amount of wire in the magnetic field. This means that more wire experiences the changing magnetic field, which induces a greater EMF
