1. What affects the strength of an electromagnet? By: Merly Lopez

2. Hypothesis  If I put an electromagnet in an oven, my results would PROBABLY be that the electromagnet will be less stronger. Then, if I stick it in a cooler the electromagnet might be stronger than before.

3. Research  Forces  Electromagnetism  Magnet Fields  Magnets  Electromagnets  Electric Current (Magnetic Dipoles)

4. Independent Variable  Everybody knows that the independent variable is the variable you are purposely changing.  In this case the independent variable is the temperature.

5. Dependent Variable  A dependent variable is the variable that is changing because of the independent variable.  My dependent variable is the strength of the electromagnet

6. Controlled Variables  The amount of time I wrap the wire around the battery  The type of battery  The thickness of insulated wire  Amount of space in room  Size of nail

7. Results/Data I counted the number of paperclip each magnet attracted. I didn’t change the temperature of the heat. Nor did I change It for the cool, the purpose was to see if the strength changed Between cool temperatures and hot temperatures. I put the Electromagnet in the oven with 90 degrees Fahrenheit for 3 min. For the cool I Put the electromagnet in the freezer with a temperature of 50 degrees Celsius for 3 min.

8. Conclusion Although my guess of electromagnets being stronger when cooler was incorrect, that wasn’t my question. My question here is “Does temperature affect the strength of an electromagnet”, I was correct it does. Though the warmer it is the stronger it is.
