Strength+of+Electromagnet

Broad Question
does the voltage of the battier effect the strength of a electromagnetic

Specific Question
does the voltage of the battier affect the strength of a electromagnet

Hypothesis
yes it will affect the strength of an electromagnet

Independent Variable:
battery voltage

Dependent Variable:
strength of electromagnet

Variables That Need To Be Controlled:
length of the wire, metal tube

General Plane
what i am going to do is get a1.5 volt battery 3 volt and 9 volt battery and see witch has the most affect on the electromagnetic

Experimental Design
(add the correct headings from the experimental design page before beginning)

Resources and Budget Table

 * Item || Number needed || Where I will get this || Cost ||
 * 1 || copper wire ||  || na ||
 * 1 || nail ||  || na ||
 * 5 || paper clips ||  || Na ||
 * 3 || batteries ||  || Na ||

Detailed Procedure
1. first you need a 1.5 volt battery some copper wire plus a nail and some paper clips. 2. Then you take the copper wire and wrap it around the nail about 50 to 60 times but lave some extra to put on the battery. 3.Then you put a paper clip on the nail and if it stays there you have done it right and just keep adding paper clips in till they start to fall off 4. do the same with different battery's and record the data
