- The formula I am using for this is mg = Fg = Fm = A*B^2/u0 (permeability constant); B = magnetic field strength. Manipulated is Fg, and responding is A (the area).
I'm trying to conduct an experiment where I calculate the magnetic field strength of a magnet, by comparing the levitation distances between two magnets. My experiment involves using different masses to anchor down magnetic repulsion between 2 magnets. Fg = Fm.
The formula I am using for this is mg = Fg = Fm = A*B^2/u0 (permeability constant); B = magnetic field strength. Manipulated is Fg, and responding is A (the area).
The problem is I see a weird relationship between the force of gravity and levitation distance. I assume that as the mass increases Fg increases, therefore, the radius should decrease as well. This isn't true for this equation. Can anyone explain why or suggest a different approach to what I am doing?
