Broad Question
What is magnetism?

Specific Question
What is an Electro-Magnet and how can i vary its strength?

Dependent Variable:
Magnetism

Variables That Need To Be Controlled:
Size Of Bolt Number Of Coils Type Of Wire

Hypothesis
I think that a more electristy will produce more magnetisity.

**Materials List**
Materials List Bolt (iron works the best) Wire (Thick preferably copper) Battery(s) different sizes Wire Switch (optional) Electrical tape Glue

**Detailed Prorocedure**
1.) Collect all materials. 2.) Find a working space. 3.) Take wire and leave about an inch sticking out and begin to coil the wire around the nail. 4.) Cut the wire once the end of the Bolt has been reached, (cut leaving about an inch. 5.) For a stronger affect repeat step 4 and layer the coils of wire. 6.) Glue the wires in place with any kind of glue. 7.) Electrical tape around the Bolt, glue and wire. 8.) Dasychain the batteries together. Or use a single battery. 9.) Attach wire to the positive and negative terminals of the battery. 10.) Connect the battery to the two wires sticking off the bolt. 11.) Stick the now electro magnet in to a cup of paper clips, or metal shavings. 12.) Pull the electro magnet out of the cup place it on a surface and disconnect the battery from the magnet. 13.) Count the metal objects that the magnet has picked up. 14.) Record the data. 15.) Repeat steps 11-14 using different size batteries with different voltage levels.

Experimental Design
I am creating an electro magnet. Out of a Bolt some wire and some batteries. The experiment will be conducted at my house. I will be the only person conducting my science experiment. And I will not be partners with anyone else and I won’t be working with anyone else. I will need to do about two experiments, for each battery. The data that I collect will go on to a spread sheet then later in to a computer to be recorded. I plan to document my process by righting down what I’m going to do before I do it and doing my experiment exactly how I wrote it down and make adjustments when needed.]

Background Research
** Background Research **

.

An elector magnet’s strength depends on the number of coils of wire there is around a core and the number of volts (electricity) it put through the wire. ||  || All magnets electro or not they have a North and south side. Two of the same side will repel but when a north and a south side are put together they will stick together. ||  || A magnet is made up of atoms. And when a piece of metal is away from a magnet the atoms in the metal are scattered, but when a magnet is placed near the metal the atoms bond together. Like the atoms in the magnet. Once all of the atoms in the metal have boned together they from a north and south pole. Witch become magnetic and attract to the magnet. When the magnet is pulled away from the metal the atoms in the metal scatter again. ||  ||

An electro magnet creates a magnetic field around a center through a wire using electricity. ||  ||

Conclusion
The original pourpous of this experment was to vary the strength of an electro-magnet. The results of the experment were thats as the voltage went up the magnisity increesed.

Discussion
====My hypothesis was that as the votalage inceesed the magnisity would increese too. My results sport my hypothesis. A trend that showed up in my data was that the more voltage that was curclated through the magnet the stronger the magnisity. The reaktionship between my independnt vairable (number of volts) and my dependnt vairable are that the more electristy that was put in to the magnet the stronger the output of magnisity is. I think that the tests waant very smoothly because I tryed alot of different things. it was trial and error most of the time. If i could inprove on anything i would have tested bigger numbers of voltage. An intresting future study might be to see how high of voltage can be put into an electro magnet with out it shorting out.====
