This is a blog I was suppose to do last week but I wasn’t there for a reason that i’m definitely not gonna tell you random people. Haha I’m joking I won’t tell though. They did it last week and did it yesterday. I came back yesterday and I was confused but someone explained it to me. Now I have to explain to my twin sister which will take forever but that’s ok.
Aim: To make an electromagnet
Research: youtube video
Equipment:
- Big nail
- Wires with alligator clips
- Variable resistor
- Power Supply
- paperclips
- sellotape
Method:
- Wrap one wire around the nail as much as possible, and sellotape it so that it doesn’t unroll. This is the electromagnet.
- Connect the power supply in series to the variable resistor and the electromagnet.
- Change the voltage on the power supply, and the resistance on the variable resistor so that the electromagnet works.
- Pick up some paperclips.
- Take a photo of everything for your results.
Results: Photos of everything, and the magnet holding up the paperclip. (I did it I just didn’t have my phone or anything to take a photo with)
Discussion:
- How many paperclips did you pick up? None
- Is that a strong magnet? Not really
- How could you make a stronger electromagnet? By more electricity
- What happens when you turn the power supply off? I don’t know I ain’t Einstein
- How do electromagnets work? Electricity
- How do electric motors work? I don’t know bro sorry teacher didn’t mention all this when he was explaining haha.
