Hypothesis
If I put an electromagnet in an oven, my results would be that it’s strength would change, then it will pick up more paperclips than usual.

Research Paper
Electromagnetism- Electromagnetism is the force that causes the interaction between electrically charged particles; the areas in which this happens are called electromagnetic fields.
Magnetic Field- A magnetic field is a mathematical description of the magnetic influence of electric currents and magnetic materials.
Magnet- A magnet is a material or object that produces a magnetic field.
Electromagnet- An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current.
Electric current- Electric current is a flow of electric charge through a medium
(Magnetic Dipoles)

Research Paper (cont.)
An electric current flowing in a wire creates a magnetic field around the wire. To concentrate the magnetic field, you wrap a wire (I used insulated wire) around an iron core (I used a nail). It then produces the magnetic field making it pick up the paperclips.
The magnetic field of an electromagnet is created by the flow of electric current through a coiled wire. The higher the temperature is, the greater the resistance that’s in the wire, which means less current and a weaker magnetic field.

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

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

Controlled Variables
The amount of time I wrap the wire around the battery
The type of batteryThe thickness of insulated wireAmount of space in roomSize of nail

Procedures
Gather up all materials.
Create an electromagnet
Put it in the oven for 3 min on 90 degrees Fahrenheit.
Then, put paperclips on a flat surface and record how many paperclips the electromagnet attracts.
After, let the electromagnet cool and then put it in the refrigerator for 3 min on 30 degrees Fahrenheit.
Then, repeat the 4th step.

I counted the number of paperclip each magnet attracted.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.

Conclusion
My hypothesis was accepted, temperature does affect the strength of an electromagnet.
