Do magnets attract objects in a straight line?

a.) magnet dipole - magnet dipole
b.) magnet dipole - electric charge
c.) magnet dipole - metal molecule
d.) magnet dipole - charged metal molecule

Will any or all of these combination result in a second particle move in a straight line or some kind of a spiral, having in mind Lorentz force (magnetic force of a moving charge) act perpendicular to both velocity and magnetic field vectors?
