Hi, I'm trying to calculate the flux density of a magnet, I can get all but one of the values needed to calculate it. Does anyone know how/where to get the z(distance from a pole face on the symmetrical axis) value?

z is just a variable. It looks like you have an equation there which would work along the z axis for varying distances, no?
BTW, is this for schoolwork or a hobby project?
No, it definitely changes with distance z. It looks like this:Bri1 said:Thanks for responding, It's for school but it feels more like a hobby, I was thinking of just assuming a value for z. I'm studying mechanical engineering so electrical isn't my strong point. But I believe it might be a set value, maybe a distance from the pole face to the height of the flux field? but then I don't know the height of the flux field anyway
My reason for thinking its a set value is because the flux density of the magnet shouldn't change with respect to z not so?
Flux density, B, of a cylindrical magnet is a measure of the strength of the magnetic field produced by the magnet. It is defined as the amount of magnetic field per unit area.
The flux density, B, of a cylindrical magnet can be calculated by dividing the magnetic flux, which is the total number of magnetic field lines passing through a given area, by the area itself.
The flux density, B, of a cylindrical magnet is affected by the strength of the magnet, the size and shape of the magnet, and the distance from the magnet's surface.
The flux density, B, of a cylindrical magnet can be measured using a device called a gaussmeter, which detects and measures the strength of a magnetic field.
The flux density, B, of a cylindrical magnet is directly proportional to its magnetic field strength. This means that as the magnetic field strength increases, so does the flux density.
