Magnetic molecules can be considered as nanoscale magnets. Remotely controlling the direction in which they rotate may intuitively be difficult to achieve. However, physicists have just demonstrated that it is theoretically possible to do so. They have shown that a change of direction in the circular polarization of an external magnetic field leads to a change in the direction of the mechanical rotation of the molecule.
