Magnetism Tinker Lab : Part 2

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
Hey again guys! Today I will be showing you my projects.

JUMPING TOY
~~~~~~~~~~~~~
This toy was pretty easy to make, I just needed....

- Tape
 - Small Toy
 - Bottle Cap
  - 2 Ring Magnets
 - Paper
First, I took the bottle cap, and taped a ring magnet on the inside of it. To make it bounce, I flipped the magnet to repel the magnet in the bottle cap, then I taped that magnet to the piece of paper. I completed the toy by taping the small toy to the bottle cap.



HOME-MADE COMPASS
~~~~~~~~~~~~~~~~~~~~~
This project was a bit challenging, but I was able to make it.

- Bowl of Water
- Cork
- Paper clip
- Ring Magnet

I took the paper clip and bent it straight. To make the paper clip work like a compass needle, I magnetized the paper clip with the ring magnet. Then I stuck it through the middle of the cork. It took a couple of tries, but I managed to get it through the cork. I gently put the cork in the bowl of water. When it stopped spinning in the bowl, it was pointing North/South. Then I used the magnet to see if the needle would follow the magnet.













WACKY PENDULUM
~~~~~~~~~~~~~~~~~~
This project is my favorite one. Here are the items I needed.....

- Pencil
- Tape
- String
- Straw
- Grey and Orange Foam (Small Hole)
- Ring Magnet
- Tinker Crate Box
- Scissors

To make the base, I flipped the tinker crate box to the side so the long sides are facing up. The pendulum needed a place to hang, so I taped the pencil on to the tinker crate box. The pendulum was pretty easy to make. I put the foam on the magnet, orange on the top and grey on the bottom. Then I cut the straw into a small piece, and slid it into the magnet. I hung it by slipping a piece of string into the straw, and tied it on by looping it around the string at the top. To finish the pendulum, I tied and taped it on the pencil. Another magnet that repelled the pendulum had to be on the surface so the pendulum would move in different directions. Here is the video of all of the magnet projects.



Do you know what a magnetic field looks like? If you were wondering what a ring magnets field was like, it would probably look like the picture below. When you feel the magnets attracting each other, that means they are within the magnetic field. The size may vary depending on the size and shape.

I hope you enjoyed the post. In the next post I will have a new tinker crate to un-box. Bye!
