How should i correct speed to keep induction constant for different viscosities

Click For Summary

Discussion Overview

The discussion revolves around how to adjust the speed of a magnet falling through a coil submerged in a liquid with varying viscosities, specifically focusing on maintaining a constant induction. Participants explore the implications of different viscosities on the magnet's fall rate and the necessary adjustments to the coil or magnet strength.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant suggests using a weaker magnet or adding resistance to the coil to achieve a similar fall rate in different liquids.
  • Another participant expresses uncertainty about how to quantify the adjustments needed for different viscosities and questions the existence of a relevant equation.
  • There is mention of specific viscosities (1.0 and 0.50 pascal seconds) and a hypothetical coil with zero resistance, raising the question of how much resistance should be increased for the higher viscosity liquid.
  • Some participants indicate that the original question may have been overlooked or misunderstood, but they do not provide a clear resolution.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best approach to adjust for viscosity differences, and multiple competing views on how to achieve constant induction remain present.

Contextual Notes

Participants express uncertainty about the mathematical relationships involved and the specific factors that should be considered when adjusting the setup for different viscosities.

So i am going to be dropping a magnet through a coil that is a submerged in a liquid. Say that this liquid is 100% lemon juice, how would i get the magnet to approximately fall through the coil at the same rate for the submerged coil and a coil that is not submerged?

Does my question not make sense or is something wrong with it?
 
I don't know, it may have been overlooked... but there doesn't seem to be much to it. You'd just use a weaker magnet, or add resistance to the coil, when it's falling through the liquid.

I have lots of ideas on how to do it but I do not know by what factor, or how to get viscosity into the equation.
 
Its been a week since my original post, is this in the wrong section?

I accept with information: it may have been overlooked but there doesn't seem to be much to it. You'd just use a weaker magnet, or add resistance to the coil.

Again, I already have different ideas about how I should adjust the setup to balance the viscosity, but I do not know by how much I should adjust it. Say I have liquid with a viscosity of 1.0 pascal seconds and another with 0.50 pascal seconds, I am using a hypothetical coil with zero resistance, by how much should the resistance be increased for the substance with viscosity of 1? Is there no equation for this?
