View Full Version : How should i correct speed to keep induction constant 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?
