Supplies- 26 gauge copper wire a plastic or styrofoam cup stack of neodimium magnets or a tall magnet one paper clip broken headphones (only need the headphone jack) one roll of tape one piece of paper pliers scissors hot glue gun or super glue Steps to Make A Electromagnetic Speaker
cut paper to 2 inches tall and 6 inches long
roll paper around your stack of magnets and attach tape
repeat step 2
take some wire and coil 80 times around the paper roll, leave 2 inches of wire on both ends
use some hot glue to make sure the wires do not uncoil
use pliers or tweezers to pull out the paper inside the second paper roll
cut four slits on the paper roll and push the slits outwards
get the paper roll and glue it to the bottom of the cup
cut the cup around the paper roll so that you get a circle out of the base of the cup
cut a ring with the width of 1cm around the hole,the ring we are cutting won't be used anymore
cut a circle out with tape which is just bigger than the hole in the cup
attach tape inside the cup right on top of the hole, the sticky part should face the bottom of the cup
attach the paper to the cup
straighten out the paper clip with pliers
bend the paper clip to attach to top of the paper roll
attach the magnet to the loop created on the paperclip and the magnet will stick to the paperclip
insert the magnets into the coil and hold the paper clip and glue it to the cup
use the hot glue gun to glue the paperclip to the cup
use a lighter to burn off insulation off the ends of the wires,you could also scrape it off with scissors
take the headphones and cut off the jack with about 4in of wire
the black wire is the ground and yellow and red wires are the other pole
attach an alligator clip to the black wire and attach the other alligator clip to either red or yellow wire and if your wires are not color coded then you need to experiment and see which ones work for you
attach the other ends of the alligator clips to the wires coming from the coil of the speaker
connect the headphone jack to your phone and play music
Explanation- What does it do?-We made a speaker,the speaker should be able to play music loud. How does it work?-The speaker should be able to plug into your phone and play music from the cup used as the speaker. What does this have to do with Electromagnetism-This relates to Electromagnitism because it's electric,we built it ourselves and we used specific wires and tools to make this connect to your phone to play music.
