On September 16, an experiment was conducted in our library laboratory «Entertaining Science» that helped to understand the power of magnets. Everyone can do this experiment at home, because all you need to implement it is one AA battery, a magnet and some copper wire. Experience shows how these items can be used to make an electric motor. The electric motor from the battery starts working because the movement of charged particles (electric charge) that has arisen in the wire is affected by a magnetic field that deflects the direction of their movement. In physics, this deviation is called the Lorentz force. When the direction of the current strength is perpendicular to the direction of the magnetic field lines, the particles move in a circle.
