2. Electromagnet
Today we will be making an
electromagnet

3. This is what our Electromagnet will look like.

4. We will use Iron Nails

5. Enameled Copper Wire

6. Batteries

7. Paper Clips: they will be picked up with our
magnets we make.

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,

10. Your Electromagnet, your copper wire has
five turns.

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

13. Your Electromagnet Still Looks Like This,
Now With TEN turns.

14. Ten Turns
How many paper clips can your magnet pick up NOW?
Write it down.
Ten turns = __________paper clips.

15. Unwind Your Copper Wire
Unwind your copper wire.
Then wind your copper wire
around your nail ONLY TWICE.
That is TWO TIMES!

16. How Many Paper Clips With TWO Turns
How many paper clips can your magnet pick up now?
Write it down.
Two turns = ______________paper clips.

17. What is the relationship of turns to how
many paper clips you can pick up?

18. The more turns you make, the stronger your
magnet will be.

19. Take a Look at this Giant Electromagnet

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.

31. State Standards for Science Michigan Department of Education
● 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.
