1. The Effects of the Number of Loops on the Generated Electric Current By LaQuean Lands

2. Hypothesis If the number of loops increase then the generated electric current will decrease.

3. Materials 4-1cm x 2cm x 5cm bar magnet 1- #30 200ft magnet wire 1-mini incandescent lamp 1- toilet paper roll 1- large nail (8cm or more)

4. 5-Step Procedure 1)Gather materials and come up with an hypothesis.

5. 5-Step Procedure 2)Take wire and wrap it around toilet paper role 3 times.

6. 5-Step Procedure 3)Connect ends of wire to magnet. Test and record what happens.

7. 5-Step Procedure 4)Repeat step 2 and 3 again two times, except wrap wire 6 times then 9 times.

8. 5-Step Procedure 5)Record data and come up with a data table. art
