The Effects of the Number of Loops on the Generated Electric Current By LaQuean Lands
Hypothesis If the number of loops increase then the generated electric current will decrease.
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)
5-Step Procedure 1)Gather materials and come up with an hypothesis.
5-Step Procedure 2)Take wire and wrap it around toilet paper role 3 times.
5-Step Procedure 3)Connect ends of wire to magnet. Test and record what happens.
5-Step Procedure 4)Repeat step 2 and 3 again two times, except wrap wire 6 times then 9 times.
5-Step Procedure 5)Record data and come up with a data table. art
