Jades Project

Hi this is Jade, I am doing a science fair project, this is what it is and how it works
It is a Flashlight that turns on with an Electromagnet.

First there is a switch that turns on and off the project, the wire that is connected to the switch leads to 12 D batteries, at the other end of the batteries there is another wire that leads to the electromagnet and back to the switch. The more wraps you have the more batteries you would need, the less wraps you have the less batteries you would need, the wire goes around about 400 to 500 times. The electromagnet is made of half a pen and electrical wire wrapped around it. The electricity keeps going around in circles in the solenoid and creates a magnetic feild, that field pulls the secondary switch.

There is a wire that is connected to the electromagnet and it goes to two different batteries and takes electricity and goes to the flashlight wire that leads to the light bulb. The light bulb has a thin wire in it called a filament, that thin wire gets so hot it makes a glow, the glow reflects off of aluminum foil and makes it brighter.

I have 12 D batteries in the solenoid because it is just about the right amount. If you have more batteries it could burn up the wire and the electromagnet would be junk, if you had less it would not have enough electricity to pull the switch.

Jade, that is so neat! Good job in explaining it! When is the science fair? After you have it, you should let us all know how it went!

Congratulations on this great project! Thanks for sharing it with us. You will do great at the science fair.

Great work on the project! Science fairs are so fun, but can be so challenging. We just finished one here and it was quite interesting trying to find the supplies we needed. Good for you!

All grandma can say is "Wow". A good explanation. Let us know how
the science fair goes. dk
