Magnetic Forces

  1. Oct 14, 2007 #1
    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?

    The magnetic force only acts on moving charged particles, but the paperclip has moving charged particles inside it... :wink:

    Then how would you determine the force that is acting on the paper clip as a whole.

    Can consider that the paper clip DOES have some electrical charge, just that the net charge between the paper clip and the environment is zero.

    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.
