How do magnetic fields affect the rate of flow of water?Featured science projectScience project video

Observation

The results show that the flow rates of both the salt solution and tap water are being reducedwhen a  magnetic field is being applied at the bottom of the burette. The flow rate of the salt solution is lower than that of the  tap water under the influence of a magnetic field.
 

Condition Time taken for 200ml to flow out of burette (seconds)
  Tap water Salt solution
Without magnets 25.5 25
With magnets 24 24

Plot the results of your observation into a graph, as shown below.
