What mechanism consists of a coil of wires that rotates in the field of action of a magnet?

1) If the coils of wires are set in rotational motion (with the help of a steam turbine, for example), then the magnetic flux of the magnetic field of a nearby magnet that penetrates it will cause the electrons to move in it. That is, an electric current will appear in it. This current can be taken out of the coil with the help of special devices (brushes) and used by different consumers of electricity. In this case, the mechanism consisting of a coil of wires rotating in the field of action of a magnet is called a generator of electrical energy.
2). If an electric current is already flowing through the coil, then, interacting with the magnetic flux of the magnetic field of a nearby magnet, the coil will be able to rotate objects attached to it on a common axis (for example, such movement is transmitted to tram wheels using transmission mechanisms). In this case, the mechanism consisting of a coil of wires rotating in the field of action of a magnet is called an electric motor.
