The left figure shows an object rotating due to a magnetic torque. The white arrow indicates the object's magnetic moment and the gray lines represent magnetic field lines. The figure on the right shows an object moving due to a magnetic force created by a magnetic field gradient [16]. The region to the right of the object has a greater density of field lines which corresponds to a higher magnetic field strength.
