Part #2: 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. it comes off of the launcher (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 showing up in the form of heat
(d) The instructor next carefully drops the other metal ring onto the launcher. Note this ring has a gap, so it does not make a complete circle. Briefly describe what happens to the non-complete ring. nothing happens (e) Why did the two rings behave so differently? Hint: It is not because they are made of different materials, since they both conduct electricity. Because the ring with the gap has no current through it because its not a complete ring. (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. first experiment a (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. when ring was placed around launcher is the power a sudden was on ring jumped which shows Change in the field created current (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.
