Electromagnet - Science

Hello, guys today I will be sharing what we have been doing in Science. We have been learning about electricity and electromagnetics. We did an experiment to see how an electromagnet works. 

What is an ELECTROMAGNET?

An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity. 

EXPERIMENT

Step 1: Wrap a coil of insulated copper wire around the nail and make sure the ends are sanded down. 

Step 2: Create a circuit with a power supply, light bulb, switch and you're electromagnetic all connected in series. 

Step 3: Turn on your circuit and see how many paper clips you can pick up. 

What does the electricity do to make nails magnetic?

Wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet, we used copper. When the electric current moves through a wire, it makes a magnetic field.

What is insulated wire? Why must we use wire that is insulated? 

An insulated wire is a non-conductive material or some kind of material that resists electric current. It surrounds and protects the wire inside. This protects the wire from the environment or the environment (like people) from the wire. It is a key safety feature in wiring.

At first, our experiment was not working because our wire wasn't working and when we got a better wire the paper clips were attached to the copper wire and nail. As we put the nail wrapped with copper over the paper clips the nail began to vibrate. I found that very interesting and it didn't take long for all the paper clips to be attached to the nail. In conclusion, this experiment was very excited my favourite part was when the nail started to vibrate and collect all the paper clips. Thank you for reading and have a lovely day. Bye!
