Magnet- work-confusion

  1. Jul 3, 2006 #1
    Lorentz force law tells us that workdone by magnetic force=0.Griffiths illustrates an example where work is done by the battery in a circuit.But I am intersted in something more.Who does the work of lifting some magnetic material when we use natural magnets?What is the way of energy conservation?What is the origin of force?
