So I figured that it was the connection between the ends of the batteries with the wires that didnt allow for the electric current to pass through to the wires. So I improved it by making sure the paper clips are in full contact with the extruded ends of the battery and stabilized its position with more tape.]]> 2023-01-04 05:24:15 UTC https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433159753 xiatian_liu https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433168209 Copper wires are conductors that electric current can pass through. Sanding off the copper of the wires gets rid of the insulation to improve the flow of the electric current. The copper wires then makes a coil, which helps create torque from the electric current, thus, the circle serves as a magnet from the electricity generated. ]]> 2023-01-04 05:38:45 UTC https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433168209 xiatian_liu https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433170243 The magnet serves as a magnetic force to move the copper circle at the top. When spinning the wires, the magnet and the magnetic force from the electric currents of the copper wires spins the copper circles at a very fast speed since magnets and the magnetic field attracts and thus, making the copper wire spin.]]> 2023-01-04 05:41:50 UTC https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433170243 xiatian_liu https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433173980 The paper clips are made from iron so they are conductors of electricity, meaning electric currents from the battery can pass through the paper clips and direct it through the copper wires. This also serves as a vertical structure to hold up the copper circle (the part that spins) above the magnet.]]> 2023-01-04 05:47:51 UTC https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433173980 xiatian_liu https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433177847 Batteries stores chemical energy and converts it to electrical energy. The chemical reactions in batteries involve the flow of electrons that generates electrical currents. The current flows out from the positive side and enters from the negative side of the battery so that an electric circuit works.]]> 2023-01-04 05:53:46 UTC https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433177847 xiatian_liu https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433183051 Electromagnetic induction is creation of magnetic force through flowing electrons as well as the creation of electric currents through a magnetic force.

Thus, the flow of electrons create a magnetic field around the coil. The electrical resistance from the changing magnetic fields creates internal friction from the magnetic fields that heats up the stove. ]]> 2023-01-04 06:20:53 UTC https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433194500 xiatian_liu https://padlet.com/xiatian_liu/o8bp43mlw2iixtiy/wish/2433327229 In headphones, the variations in electric current flow produces various magnetic fields around the electromagnet.
