### Week 3 summer powerpoint

1. 1. Ms. Miscisin 4th Grade Science 2013-2014 School Year
2. 2. Electromagnet Today we will be making an electromagnet
3. 3. This is what our Electromagnet will look like.
4. 4. We will use Iron Nails
5. 5. Enameled Copper Wire
6. 6. Batteries
7. 7. Paper Clips: they will be picked up with our magnets we make.
8. 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. 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. 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. 12. Now wind or turn your copper wire TEN times around your nail
13. 13. Your Electromagnet Still Looks Like This, Now With TEN turns.
14. 14. Ten Turns How many paper clips can your magnet pick up NOW? Write it down. Ten turns = __________paper clips.
15. 15. Unwind Your Copper Wire Unwind your copper wire. Then wind your copper wire around your nail ONLY TWICE. That is TWO TIMES!
16. 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. 17. What is the relationship of turns to how many paper clips you can pick up?
18. 18. The more turns you make, the stronger your magnet will be.
19. 19. Take a Look at this Giant Electromagnet
20. 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. 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. 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.
