How do magnetic fields affect the rate of flow of water?

Introduction

sources

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. Water is one of the most abundant substances on Earth. The experiment will be done using salt solution and TAP WATER, with a magnetic field as well as without a magnetic field.

magnetic field can act through the air. The magnetic field from an external PERMANENT MAGNET will have its flux lines curved away from the diamagnetic materials, and flux lines mean when the negative pole magnet located with another negative and the positive with another positive in the same direction. Repulsion happens between the magnetic fields. The magnetic field will also be slightly weakened by the diamagnetic material.

Water is diamagnetic. It is able to slightly attenuate and repel the magnetic field from an external permanent magnet. This weakening effect is greater when salt water is used. In theory, if water is able to repel a magnetic field, it should then be possible to slow down the rate of flow of water through a narrow channel, by introducing a sufficient strong magnetic field along the channel.

Question

How do the magnets affect the water?

Hypothesis

Under the affecting of a magnetic field, the salt solution will have a faster the rate of flow of water than the TAP WATER with mgnets

Further Work

Conclusion

This experiment was very exciting. I want to do another experiment. The another experiment is about The effect of different Electrodes and Electrolytes on voltage. I have another question. Magnet that can work from installing of chemicals with metals?

The hypothesis that salt solution has a faster rate of low of water than tap water with magnets under the affecting of a magnetic field is correct.

The magnetic field has an effect on the tap water mix up with salt.

Results

Materials

procedure

- 400 ml of TAP WATER

- 50 grams of salt

- 2 beakers

- 1 burette

- 1 measurement cylinder

- 1 stop watch

- 2 large PERMANENT MAGNETS

1. The independent variables of this science fair project is the type of water used (salt solution and TAP WATER) and whether the magnetic field is or is not present. The dependent variable is the time taken for the fluid to flow out of the burette. This is measured using a stopwatch. The control variables are the amount of water used, the strength of the permanent magnet used, the flow rate of the burette and the room temperature. My project is about Is the magnets has an effect on any other non-metal materials? .Is the amount of salt solution has effect?

2. The experiment will do it to show what will happen.

3. Fill 50ml of TAP WATER into the measuring cylinder. This is then poured into the burette. The flow rate of the burette is set and the same conditions will be used for the subsequent experiments.

4. The time taken for the 50 ml of TAP WATER to flow out of the burette (without any magnetic field applied) is measured. Repeat this process up to 5 times and the average time taken will be calculated and recorded in the table.

5. Step 4 is repeated by placing 2 permanent magnets at the bottom of the burette. This measurement is again, repeated 5 times for us to obtain the average timing required, which will be recorded in the table.

6. Mix 50 grams of salt with 200 ml of TAP WATER in a separate beaker. Using the measuring cylinder, pour 200 ml of salt solution into the burette. Repeat steps 4 and 5 using the salt solution. The average timing taken for 5 tests are calculated and recorded in the table.
