Magnetic Induction Experiment PH07 Objective See how a changing magnetic field can induce a current in a circuit Test how both step-up and step-down transformers work and how iron can affect the induced emf Materials Experiment Software File(s): PH07_Induction Neodymium Magnet Primary & Secondary Coils Set Large Copper Coil No-Bounce Cushion Wire Lead, Banana-Banana (2) (1 red, 1 black) Pasco Voltage Sensor WARNING: Keep magnets away from computers, cell phones, and flash drives Theory Magnetic Induction When a magnet is passed through a coil there is a changing magnetic flux through the coil, which induces an electromotive force (emf) in the coil. According to Faraday's Law of Induction: =-Nt (1)
