Electricity and Magnetism

1st question: How are magnetism and
electricity related

The telegraph
invented by Samuel
F. B. Morse uses an
electromagnet to
make noise, certain
sounds stand for
different letters. A
dot is a short sound
a dash is a longer
sound.

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.

1st question: How are magnetism and


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.
Conclusions

Part A: An electric
current has a
magnetic field and
if you coil it around
a metal object it
creates an
electromagnet.

Part B: A moving
magnet makes an
electric current.
