Investigate Faraday's law and how a changing magnetic flux can produce a flow of electricity! • Explain what happens when the magnet moves through the coil at different speeds and how this affects the brightness of the bulb and the magnitude & sign of the voltage. • Explain the difference between moving the magnet through the coil from the right side versus the left side. • Explain the difference between moving magnet through the big coil versus the smaller coil.
