  1. Electricity and Magnetism By Adon Shapiro

  2. The telegraph inventedby Samuel F.B. Morse usesan electromagnet to make noise, certain sounds stand for different letters. A dot is a short sound a dash is a longer sound. Morse code A=.-, B=-..., C=-.-., D=-.., E=., F=..-., G=--., H=...., I.., J=.---, K=-.-, L=.-.., M=--, N=-., O=---, P=.--., Q=--.-, R=.-., S=..., T=-, U=..-, V=...-, W=.--, X=--., Y=-.--, Z=--. 1st question: How are magnetism and electricity related

  3. 1st question: Howaremagnetism and electricity related • How the Telegraph works When you push down the key it gives the electrons a free path which activates the electromagnet which pulls the strip down. The strip makes a noise when it hits the nail.

  4. 1st question: How are magnetism and electricity related • I made a coil with 1,000 turns around a plastic tube and attached a light bulb to the wires. When you drop a magnet through the tube the light bulb lights up. This is a very simple generator.

  5. Part A: An electriccurrent has amagnetic field andif you coil it aroundametal object itcreates anelectromagnet. Part B: A movingmagnet makes anelectric current. Conclusions
