Hi, I'm buying magnets for a required experiment in my magnetic and electricity physics class. The supplier gives to important pieces of information: BrMax: 3850 gauss and Pull Force: 33lbs. I was wondering if there is a relatively simple formula so that I can calculate the force of the magnet at point x fromt he magnet using the gauss value. Essentially, I want to calculate the force of the magnet in Newtons. Thanks.
