Can anyone tell me how to i can calculate the amount of load an electromagnet will pull. the electro magnet has 3 poles. 1 pole is the centre core of the magnet (N) there are two adjacent poles which are on either side of the coil which are joined across the other (s) end of the core. If i can measure the gauss output from the poles and i know the surface area of the poles can i calculate the force in KG it will hold? Is ther a formula i can apply.
