If the net charge between the paperclip and the environment is zero, then how can it be measured?
By the way, thank you to everyone who has responded so far, its been a big help.
The only formulas for forces due to a magnetic field have to do with a charged body.
How can you calculate the force acting on an uncharged body?
And if there is no force, why can you pick up a neutral paper clip with a magnet?
