2. Jason also makes a home-made power supply to illuminate battery-powered glowing lightsabers. a. He realized that if he can make a magnet, then he could use it to create the power supply. First, he needs to make the magnet. Jason has a spare loop, and can temporarily borrow a 3 V battery, and an unmagnetized ferromagnetic rod. He can potentially use these materials to magnetize the rod by looping the wire around the rod and hooking the ends of it to the battery to run current through the loop. True or False b. If he figured out how to create a magnet from a piece of unmagnetized ferromagnetic material, the magnetic moments the rod are: i. not aligned at all before being magnetized and all aligned after being magnetized ii. not aligned at all before being magnetized and aligned within grains after being magnetized iii. aligned within grains before being magnetized and all aligned after being magnetized c. Jason makes a permanent magnet and wants to figure out how to use it and a conducting rod to create a voltage source to power the lightsabers. He could move the conducting rod through the magnetic field from the magnet, to result in a separation of charge across the ends of the rod. The separation of charge will result in a voltage across the ends of the rod. True or False
