For this experiment we tested how a magnets force was impacted by three different types of liquid. We used Water, Vegetable Oil and Corn Syrup.
How Liquid Impacts a Magnet Video
- 3 Glasses
- 12 Paper Clips
- 1/2 Cup Water
- 1/2 Cup Vegetable Oil
- 1/2 Cup Light Corn Syrup
Step 1 – Place three cups in a row
Step 2 – Fill the first glass with the water
Step 3 – Fill the middle glass with the vegetable oil
Step 4 – Fill the third glass with the corn syrup
Step 5 – Next, place 4 paper clips in each glass
Step 6 – You may need to gently push the paper clips to the bottom of the glass with the corn syrup
Step 7 – Test your magnet by showing how paper clips outside of the liquid are attracted to it.
Step 8 – Next, take your magnet and place it next to each glass. Notice that all the paper clips are attracted to the magnet, but that the liquid in the glass causes the paper clips to move differently.
How Does the Experiment Work?
The question answered in this experiment is how does the consistency of a liquid impact magnetic attraction.
When using water and vegetable oil, the paper clips moved through the liquid to the magnet very quickly. This is because the liquids provided very little resistance.
However, the paper clips in the corn syrup moved very slowly toward the magnet. This is because the corn syrup has a very think consistency.
The magnet still still attracts the paperclips in each of the scenarios. But the experiment shows that the thickness (also called consistency or viscosity) of a liquid impacts how fast (or slow) the paperclips move toward the magnet.
I hope you enjoyed the experiment. Here’s some printable instructions.
