Movement of bimetallic motors under chemical magnetism force

Motors are devices that are capable of converting various forms of energy into kinetic energy of their motion. Surface forces can play an important role in the movement of motors. One type of surface force is the force of chemical magnetism. If a loop with current occurs during redox reactions on the surface of a bimetallic swimmer, then a force acts on it in a non-uniform magnetic field. The nature of this force is in no way related to the magnetic properties of the material from which the swimmer is made but is determined by the action of the Lorentz force on moving charges in a magnetic field. Here we demonstrate various methods for controlling the speed and orientation of bimetallic swimmers that move under chemical magnetism force. The results of the study show that depending on the mutual direction of the magnetic force and the force of chemical magnetism chemical reactions can contribute to both acceleration and deceleration of the swimmer in a non-uniform magnetic field. By changing the concentration and type of electrolyte, the type of metals from which the swimmer is made, and the pH of the solution, it is possible to control the orientation and speed of the swimmer. These results open up new possibilities for the direct conversion of the chemical energy of the “fuel” into the kinetic energy of moving motors.
