well i hope I am posting this in the right section, I am new here.
im making some electromagnets for a personal project I am doing but i want to get all the calculations done before i get all the materials and actually build the thing.
i need to know what/if there is an equation to find the permeability of the core material of an electromagnet. the type I am making are solenoids and i was thinking of using ferrite (alpha iron) as the core material. so its going to be a pipe/tube of ferrite with insulated copper wire wrapped around it and a patch of air through the middle.
i searched around on the internet but couldn't find anything usfull, oh and it needs to be an equation that's doesn't use the magnet flux density because I am trying to find the permeaility so i can then find the flux density which i can go on to find the force it will pull an object relative to its distance from the magnet. ill work out the last bit after i get the permeability.
