How to make an ammeter with a battery
Once you have all the materials assembled you can begin to build your own ammeter. Start by winding themagnetic wire around the toilet paper tube. You will want to make sure that there is at least 100 coils around it. They should be tightly wound around the tube without crushing it. Leave about 0.5-inches of wire. Place the tube on top of a piece of cardboard and secure it with hot glue. Remove the ends of the magnetic wire with a piece of sandpaper to expose the wire inside the insulation. Take an end of the magnetic wire and form a loop in it. You will need to twist the end several times. Make a small square with the aluminum foil and wrap it around the end that you just. Now that you have the magnets in place you should rotate the whole assembly so that you can only see the very edges of the discs. This means the ammeter is at zero. Cut small slits into the toilet paper tube near the wires. Place 2 magnetic discs on the thread on the inside of the tube and suspend them in the.
