Physics

  1. Consider the following situation. With the power supply off,the current limit one-half of a turn and the voltage knobcompletely counterclockwise, a coil is connected to it. A secondarycoil is placed just in front and connected it to a galvanometer. Ifyou gently increase the voltage of power supply, explain what youwould observe in the galvanometer. Would the needle deflect?Why?
  1. If the secondary coil is moved away from the primary coil,would the deflection of the needle be larger, smaller, or thesame? Explain!
  1. In this experiment, you moved the bar magnet closer to or awayfrom the coil while keeping the coil stationary. How would theresult change if the moved the coil while the bar magnet is kept atrest? Explain!

If you move both the bar magnet andthe coil, how would this motion change the result you observed inthis experiment. Explain!
