Part #12: Magnetic Induction Faraday discovered an important link between magnetism and electricity - specifically, magnetic fields can be used to generate electric current. This section deals with some of the specifics of that discovery and how it is applied in everyday life. First we examine the magnetic "launcher" (see Figure 6-2). The launcher has a solid, cylindrical iron rod at the top. Figure 6-2. Magnetic Launcher with Metal Ring. (a) The instructor puts a complete metal ring around the launcher and turns on the power. Briefly describe what happens. (b) Next, the instructor places the complete metal ring slowly on the launcher. Briefly describe what happens. its floating (c) The instructor next hands the ring to a student. What does the student say about the ring? What explains this observation? feels more warm to the touch, because power is being released and it is show up in the form of heat
(f) Faraday found that while a strong magnetic field alone did not generate voltage, a change in the magnetic field did. List examples from the above experiments that show this effect. (g) Electric current moving in circles creates magnetic fields. Which of the above experiments shows the creation of a magnetic field by using electric current? Briefly justify your answer. (h) For electric current to flow, there must be (i) a voltage and (ii) a closed circuit. List examples from the above experiments that show an example(s) where voltage was present but current still did not flow.
