8. An Electromagnet Has
● 1. A power source (we are using a battery)
● 2. A conductor (we are using a wire)
● 3. A core (we are using an iron nail)
● The Paper Clips will help us measure the
strength of our magnet.
9. Steps
● When you get your supplies, wind your copper wire around
the nail 5 times. This is called five “turns.”
● Connect the ends of your copper wire to each end of the
battery.
● You now have an electromagnet.
● Again, your electromagnet will look like this,
11. Use Your Magnet
● Try to pick up paper clips. How many paper clips will your
magnet pick up?
● Write down how many paper clips your magnet picked up
with five turns(winds).
● Five Turns =_____________paper clips.
12. Now wind or turn
your copper wire TEN
times around your nail
20. We Made a Small Electromagnet Today Using
● 1. A power source ( a battery)
● 2. A conductor ( an enameled copper wire)
● 3. A core (an iron nail).
● We measured its strength by seeing how many paper clips
it could pick up.
21. We Learned
●The more turns =
the stronger the
magnet.
● We saw that with more turns made to the wire, the stronger
our magnet became.

● P.EN.04.52 Demonstrate magnetic effects in a simple electric circuit.
● Instructional Clarifications
● 1. Demonstrate is to show through manipulation of materials, drawings, and
● written and verbal explanations the magnetic effects in a simple circuit.
● 2. A wire carrying an electric current creates a weak magnetic field. A
● magnetic compass will show the effects of the magnetic field.
● 3. A simple electromagnet has the same general characteristics of a circuit,
● including a power source (battery or generator), conductor (wire), and a
● wire wrapped core.
● 4. An electromagnet is produced by wrapping a wire around a core (nail) and
● attaching the ends of the wire to a battery.
● 5. The strength of an electromagnet is increased by wrapping more coils of
●
wire around the nail or increasing the amount of current.
