#### Transcript of Do magnets affect the rate flow of water?

Overview
Abstract

This science fair project investigates how the
magnetic field emanating from a permanent magnet will affect the rate of flow of water through a narrow passage.
The experiment will be done using salt water and tap water, with a magnetic field as well as without a magnetic field.
Hypothesis

Under the influence of an adequately strong magnetic field, the
salt solution will have a slower rate of flow than the tap water
Diamagnetism
Diamagnetism is the behavior of certain materials that forms an opposing magnetic field when it is exposed to an external magnetic field generated by a permanent magnet. Diamagnetic materials normally have a relative permeability of less than 1, causing them to be repelled by the magnetic field.
BASICALLY , water is repelled by magnets (its very minimal) and that is diamagnetism.

Video Explaining Diamagnetism
This video is going to make sure you fully understand the concept of what the whole project is about.
Diamagnetism
This video shows actual FLOW CHANGE of a tap solution.
What I had to do for this project
My procedure basically consist of me measuring the flow rate times of salt and tap water under the influence of a magnet and without a magnet. I'm doing this to see which is faster and to test if the magnets affect the flow rate at all.
How do magnetic fields affect the rate of flow of water?

Doing the steps pics
(the salt solution had longer time 40.4so my hypothosis was correct.
My Work Examples Pics
(the red things in the pictures were magnets taped in place to hold on to beaker so water would pass it)
My Conclusion

The hypothesis that salt solution has a lower flow rate than tap waterunder the influence of a magnetic field is proven to be true.
